2-5(h+3)=-28

First you have to take your -5 times h and times +3.

Now you have 2 -5h - 15 =-28

Now just solve for h by either adding or subtracting your other numbers to both sides of the equation.

2-5(h+3)=-28
> 2-5h - 15 = -28
> -5h= -28 + 15 -2
> -5h= -15
> h = -15 / -5
Therefore, h = 3
Easy Peasy :)
