What is the resulting equation when the expression for y in the second equation is substituted into the first equation? 3x + y = 1
y=6 - 4x

Ox+6y=1
Ox+6=1
Ox -X + 6 = 1
7X+6=1

Hello!

Let's solve this question with the information given to us in the question.

We were given two equations:

3x + y = 1

y = 6 - 4x

The question asks us to plug in our 2nd equation into the "y" variable of the first equation.

Plug in and solve:

3x + y = 1

Substitute "6 - 4x" for y

3x + 6 - 4x = 1

Simplify

-x + 6 = 1

Therefore, your answer would be the -x + 6 = 1 choice in your answer box.

-x + 6 = 1
