Question

how do I solve the system equation y=x+5 y=6?

Answer 1

You would plug in the 6 and have y=6+5 and your y would equal 11.

Answer 2

If y=6, plug 6 into the equation:

6=x+5

Isolate x by performing the opposite operation by subtracting 5 on both sides of the equation

The 5's will cross out on the right

5 - 5 =0 

The result on the left will be 1

6-5=1

x=1
