Question

Solve this using the elimination method 4x - 3y = 22 2x + 8y = 30

Answer 1

4x-3y=22
-4x-16y=-60
-19y=38
y=-2

Answer 2

4x - 3y = 22
2x + 8y = 30

Multiply the second equation by - 2

    4x - 3y = 22
-2(2x + 8y = 30)
-----------------------

     4x - 3y = 22
   - 4x - 16y = - 60
----------------------------
           - 19y  = - 38
Divide both sides by - 19
               y = 2
Plug 2 into either equation and solve for x.
2x + 8(2) = 30
2x + 16 = 30
subtract 16 from both sides
2x = 14
divide both sides by 2
x = 7
(7, 2)
