Hello there! :)

Answer:

x=7

*The answer must have a positive sign.*

Explanation:

Distributive property: a(b+c)=ab+ac

First, you expand.


5(x-3)=5x-15


5x-15=x+13

Then, you add by 15 from both sides of an equation.


5x-15+15=x+13+15

Simplify.


5x=x+28

You subtract by x from both sides of an equation.


5x-x=x+28-x

Simplify by equation.


4x=28

Then, you divide by 4 from both sides of an equation.


(4x)/(4)=(28)/(4)

Finally, divide by the numbers from left to right.


28/4=7

Final answer is x=7

Hope this helps!

Thanks!

Have a nice day! :)

:D
