Question

4x + y = 20
y = 3x – 2
Is (3,8) a solution to the system? Explain.

Answer 1

It's the solution for the first one, but not the second one

Explanation:

(3,8) (x,y)

The first one works, because it does equal 20

4*3= 12+8= 20

The second one does not work, because it equals 7 and not 8

3*3= 9-2= 7
