Hi there!
Solving for h is easy. Below are the steps to seeing what it's value is.
1) Simplify both sides of the equation
7/5h + -2 = -3/5h + 7
7/5h -2 = -3/5h + 7
2) Add 3/5h to both sides
7/5h - 2 + 3/5h = -3/5h + 7 + 3/5h
2h = 2 = 7
3) Add 2 to both sides
2h - 2 + 2 = 7 + 2
2h - 2 = 7
4) Divide both sides by 2
2h/2 = 9/2
h = 9/2
Hope this helps! :)
