Answer 1

For the following system, if you isolated x in the first equation to use the Substitution Method, what expression would you substitute into the second equation?

-x - 2y = -4
3x + y = 12

-2y - 4

2y - 4

2y + 4

-2y + 4

Answer 2

Would it be -2y+4?

Answer 3

-x - 2y = -4
-x = 2y-4

i.e. x= 4-2y will be substituted

Answer 4

So the answer is 2y-4?

Answer 5

No it is -2y + 4

Answer 6

or 4-2y
