Question

use the second equation to make a substitution for x in the first equation.

3x + 2y = 7
x - y + 3 = 0

What is the resulting equation?

Answer 1

What steps have you taken so far?

Answer 2

+y-3. +y-3
X=y-3
3x+2y=7
3(y-3)+2y=7
3y-9+2y=7
5y-9=7

Answer 3

3x + 2y = 7
x - y + 3 = 0
What is the resulting equation?
x-y+3=0


+y-3. +y-3
X=y-3
3x+2y=7
3(y-3)+2y=7
3y-9+2y=7
5y-9=7

Answer 4
