How Do I Solve This Algebra Problem?
-2(x + 3y) = 5 write it in slope-intercept form. Then find slope and y-intercept of the line determined by the equation. -2(x + 3y) = 5 -2x - 6y = 5 Adding 2x on both sides you will get - 6y = 2x + 5...
How Do I Solve This Algebra Problem?-6x - 36
The expression can be factored: -6x - 26 = -6(x+6) There is nothing to solve. -6x - 36 = 0 -6x = 36 x = -6
How Do I Solve This Algebraic Equation Showing All Steps 5/4x-3=2...
5/4x-3=2 Add 3 on both sides you will get 5/4x -3 +3 = 2+3 5/4x=5 Multiplying both sides by 4 you will get 4(5/4)x=5(4) 5x = 20 Dividing both sides by 5 you will get 5x/5 = 20/5 x =...
How Do I Solve This As A Two Step Equation -9x+1=-80?
-9x +1 = -80 Step 1 . Subtract 1 from both sides -9x = -81 Step 2 . Divide both sides by -9 x = 9 Should be -81/-9 = 9, rather than -81/9 = -9.
How Do I Solve This By The Elimination Method? What Is The Solution...
Multiply the first equation by 2 2(4x + 5y) = 2(3) 8x + 10y = 6 Note that this is precisely equal to the second equation. This means the two equations are not independent--they define the same file. The "system"...
How Do I Solve This Car Question?
Find the gas mileage any car of your choice. Let x be the number of miles driven on 50 gallons of gas. By setting up and solving a proportion involving x, find the value of x for the car that you hold chosen. State the type of car,...

How Do I Solve This Equation, 2x -4?
I would like the working out please There is no equal sign in the given text, so in that is no equation to solve. Perhaps you mean 2x - 4 = 0 (my 1st guess at your equation) 2x - 4 + 4 = 0 +...
How Do I Solve This Equation:3/2x+3 +2x/2x+3? I Think The Answer Is...
Maybe it's 3+2x/2x-3 I'm confused The expression given is not an equation. (There is no "=".) Apparently, you are asked to simplify it, rather than "solve" it. If the intended form of the expression is 3/(2x+3) + 2x/(2x+3), the terms...

How Do I Solve This Math Problem?(4y^4/27x) X (9x^5/24y^7)
I assume the middle x is intended to be a multiplication operator, whereas the others are intended to be variables. I also assume that everything to the right of the slash (/) is in the denominator. Multiply these fractions the way you would any fractions,...
How Do I Solve This Math Problem?
Graph using the intercept method: 2x + y = 4. It is simple, you need to calculate the value of x first: 2x + y = 4 2x = 4 - y x = (4 - y)/2 So from here every expediency of x will give...
