3x-4=x+10 How Do You Do It?
A solution has x on one side of the equal sign, and a constant on the other side. You can do anything you need to do to the equation to bring about that result, provided you do it to the expressions on both sides of the equal sign...

3x-4y=1-6x+8y=-2Can You Help?
Solve & answer1. There are only two solutions2. There is only one solution3. There are infinitely many solutions4. There are no solutionsShow work X=0 and y=0 3x-4y=1 x = 4y/3 -6(4y/3)+8y=-2 -8y +8y = -2 0y = -2 hence, in that are no solutions .

3x-4y=-24x+y=-1 How Do I Do This Using Elimination?
Equation 1: 3x-4y=-24 Equation 2: X+Y=-1 Equation 2 can also be written as: X=-1-Y Lets assume this is equation 3 SO: Equation 3: X=-1-Y Substituting equation 3 into equation 1: 3(-1-y)-4y=-24 Expanding: -3-3y-4y=-24 Subtracting: -3-7y=-24 Shifting -3 to the other side: -7y=-24+3 Subtracting: -7y=-21 Dividing: -y=-21/7...

3x-5(3x-7)=2(x+9)+45 Can You Help?
This is what I have so far and now I am stuck....3x-5(3x-7)=2x+18+45 30. 3x-5(3x-7) =2(x+9)+45 3x-15x+35=2x+18+45 -12x + 35 = 2x + 63 -12x+12x+35-63=2x+12x+63-63 -28=14x 14 14 -2=x 3x-5(3x-7)=3x-15x+35=35-12x 2(x+9)+45=2x+18+45=2x+63 and, 35-12x=2x+63 then, -12x-2x=63-35 -14x=28 so, x=-2

3x-5(3x-7)=2(x+9)+45?
How do you solve the problem? 3x-5(3x-7)=2(x+9)+45 3x-15x+35=2x+18+45 -12x+35=2x+63 -14x=28 x=-2 3x-5(3x-7)=2(x+9)+45 3x-5(3x-7)=2x+18+45 3x-5(3x-7)=2x+63 3x-15x+35=2x+63 -12x+35=2x+63 the next step is to get the x's alone together -28= 14x &nbs p; 2=x X+7x+10y-3x

3x-y=11 And 5y-7x=1, Can You Help?
Sure! We can solve this sett of equations as simultaneous equations. Our equations are: 5y - 7x = 1 ---- Equation I 3x - y = 11 -y + 3x = 11 5(-y + 3x = 11) -5y + 15x = 55 ---- Equation II Now, solve...

3y-21 = 12x, Can You Help?
Your question isn't very clear so I'll write a few things it could be. 3Y - 21 = 12X If you are looking for Y 3Y = 12X + 21 ... Add 21 to both sides Y = 4X + 7 ..... Divide both sides by 3 If you...

4 - 1/6 = ?Please Explain Step By Step.
4 is a whole number One way to view this is as a "borrowing" problem. It is similar to 4.0 - 0.1, for example, where on earth you must "borrow" 1 from the 4 and think of it as 10/10. Then you can subtract...

4 - X/ X-2 = -2 / X - 2, Can You Help?
First we do cross multiplication{ 1)Left side numerator to right side denominator 2) right side numerator to left side denominator} but here both side denominator are same so no need to do the second step [(4-X)(X-2)]/(X-2)=-2 (X-2) will cancel as both...

4 ( Z + 8 ) - Z . Can You Simplify?
The distributive property of multiplication over addition says you can multiply 4 times each of the jargon inside the parentheses. 4(z + 8) - z = 4(z) + 4(8) - z = 4z + 32 - z Now, the distributive...

4 1/5 *3/4 *6=?
Please help me to solve this problem and show me how you got your answer. 4 1/5*3/4*6 =21/5*3/4*6 =4.2*0.75*6 =18.9 First divide 21 with 5 you would carry 4.2. Then divide 3 with 4, you would get .75. In the end, multiply, 4.2 near .75 and 6, the answer...

4 3/8 Divided By 1 2/5 = 35/8 Times N What Is N?
(4 3/8)/(1 2/5) = (35/8)N (your given expression) (35/8)/(12/5) = (35/8)N (convert mixed numbers to improper fractions) 1/(12/5) = N (remove the factor of 35/8 from both sides) 5/12 = N (perform the reciprocal operation)

4-(2+3m)+6m+9,how To Do?
Our question is: 4-(2+3m)+6m+9 Expanding: 4-2-3m+6m+9 Simplifying: 4-2+9= 11 and -3m+6m = 3m So: 11+3m If the equation has an equal to zero within front of it. We would solve further. Solving further: 11+3m=0 Shifting: 3m=-11 m=-11/3
