Question

2. y - 8 = 15
y -0 =

Answer 1

23

Explanation:

I'm going to start by solving the first equation like so,

y - 8 = 15 (Remember what we do to one side we MUST do to the other)

+8 +8

y = 23

So know we know y = 23 What we have to do now is replace 23 for y in the second equation.

y - 0 = ?

23 - 0 = 23

Hope that helps and have a great day!
