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.
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.
