Answer:

x = 13

Step-by-step explanation:

Given

x + 15 = 28

Isolate x on the left side by subtracting 15 from both sides

x = 28 - 15 = 13

To solve this equation, just flip it around and change addition to subtraction.

So it would go from x + 15 = 28
To 28 - 15 = x
And 28 minus 15 equals 13
So x = 13
Then you plug 13 in for x.
13 + 15 = 28.
