Question

Solve the system of equations.

y = 7x + 43
y = 2x + 13


Help please, need to know how to do

Answer 1

You are given:
y = 7x + 43
y = 2x + 13

All things are themselves so:
y = y

So replace each y there with one of the equations:
7x + 43 = 2x + 13

Now solve for x, then put that answer into either of the originals and solve for y.
