Question

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

-x + 6 = 1 or
x + 6 = 1 or
7x + 6 = 1

Answer 1

You already have part of the solution; substitute the y = 6-4x for the y value in the first equation. Simplify to solve.

Answer 2

you can do this...do what Mike said...sub 6 - 4x in for y in the 1st equation, then simplify

Answer 3

k i got it thx

Answer 4

what did you get ?

Answer 5

-x+6

Answer 6

3x + y = 1
3x + (6 - 4x) = 1
3x + 6 - 4x = 1
-x + 6 = 1

Answer 7

your right
