Question

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?
Oy+2x+y=6
2x + y + 3x +4=6
2x + 3x + 4) = 6

Answer 1

2x+3x+4=6

Explanation:

You'd plug in the y-equation which is y=3x+4 into the placement of the y in the first equation 2x+y=6,

Which would then result in 2x+3x+4=6, which is the answer
