Question

Select the correct answer.

To solve this system of equations using substitution, what could be substituted in place of y in the first equation?
4x=5-2y
y-2x=7

Answer 1

Answer: y=2x+7

(this is a rearranged version of y-2x=7 from question)

Explanation:

4x=5-2y

y-2x=7

i would rearrange the 2nd value into y intercept form y=mx+b

so move the -2x to the other side of the = sign by doing the opposite, +2x on both sides to isolate the y

y=2x+7
