Question

Equation H: y = −x + 2
Equation J: y = 3x − 4

Which of the following steps can be used to find the solution to the set of equations?

−x = 3x − 4
−x +2 = 3x
−x + 2 = 3x − 4
−x + 1 = 3x + 2

Answer 1

you have 2 equations beginning "y="

so for instance
y=a
y=b

you could write a=b

so take the expression for y from the first equation and substitute it for "y" in the second

Answer 2

i'm so confused :c explain? @MrNood

Answer 3

take the expression for y from the efirst equation - and put it in place of "y" in the second
