Blababa [14]

Hi there! :)

<u><em>Answer:</em></u>

<u><em>x=23</em></u>

<u><em>*The answer must have a positive sign.*</em></u>

Step-by-step explanation:

This lesson it's about addition property of equality.

First, you add by 8 from both sides of an equation.

x-8+8=15+8

And then, you add by the numbers. Simplify and solve.

15+8=23

Final answer: → x=23

Hope this helps!

Thanks!
