# How Do You Solve By Elimination Method? 4x-3y=25 4y=2-2x

**Answer:**

Start by putting the two equations in standard form.

4x - 3y = 25

2x + 4y = 2 (this equation could be reduced to x+2y = 1)

To eliminate x, subtract 2 times the second equation from the first. This choice is determined by the coefficients of x.

(4x - 3y) - 2(2x + 4y) = (25) - 2(2)

-11y = 21

y = -21/11

To eliminate y, attach 3 times the second equation to 4 times the first. This is determined by the coefficients of y.

4(4x - 3y) + 3(2x + 4y) = 4(25) + 3(2)

22x = 106

x = 53/11

The solution by elimination is (x, y) = (53/11, -21/11)

Check

4(53/11) - 3(-21/11) = 25

(212 + 63)/11 = 25

275/11 = 25 (yes)

4(-21/11) = 2 - 2(53/11)

-84/11 = (22 - 106)/11

-84/11 = -84/11 (yes)
