-4x+5y=6 mulyiply this equation by 3
-12x+15y=18
-------------------
3x+2y=7 multiply this equation by 4
12x+8y=28
now add them:
----------------
-12x+15y=18
12x+8y=28
----------------------
23y=46
y=46/23
y=2 answer.
-4x+5*2=6
-4x+10=6
-4x=6-10
x=-4/-4
x=1 answer.

What is the solution to 1. y = 3x – 8
y = 4 – x
2. x + y = 0
3x + y = -8
(answered by Alan3354)
I am solving by using the elimination method.
-5x+y=-13
6x-5y=8
5x=8+3y
3x-4y=18
