Question

Y=3x+17, 4x-3y=-26
Use substitution to solve the system

Answer 1

The answer is X=-5 and y=2

Answer 2

x=-5, y=2

Explanation:

`y=3x+17\\\\4x-3y=-26`

With substitution, you can replace y in the second equation with 3x+17, since you know they are equal.

`4x-3(3x+17)=-26 \\\\4x-9x-51=-26\\\\-5x=25\\\\x=-5\\\\y=3(-5)+17=-15+17=2`

Hope this helps!
