For the following system, use the second equation to make a substitution for y in the first equation.

2x + y = 6
y = 3x + 4

What is the resulting equation?

y + 2x + y = 6
2x + y + 3x + 4 = 6
2x + (3x + 4) = 6

2x + y + 3x + 4 = 6 is the correct equation :)
For the following system, use the second equation to make a substitution for y in the first equation.

y = 3x + 4

substitute y = 3x + 4 into 2x + y = 6

2x + y = 6
2x +( 3x + 4) = 6

answer is 2x + (3x + 4) = 6 (last choice(
