someone help me plz

acxbox22 · Answer

since both equations are equal to y substitution would be the better option

anonymous · Answer

I can help you solve Part A. But I do not understand Part B.

anonymous · Answer

The dependent variable for both equations are "y" so substitution is the correct answer.

acxbox22 · Answer

and the point where the two lines intersect on a  graph is simply their solution

anonymous · Answer

ok thanks but I have to explain how to solve it using substitution I don't know how

acxbox22 · Answer

set the two equations equal and solve for y
