Question

Man somebody show me the steps PLZ!!!

Answer 1

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

Answer 2

How do i start :/

Answer 3

Okay so for the first part you sub y for y=3x+4

You should get
2x+y+3x+4=6

Answer 4

Then you solve for x

2x+y+3x+4=6
5x+y=2

Answer 5

Or 5x=2-y
