Verified Answer :

The answer is 10. 
1) 7h-5h-7=13
2) 2h=13+7
3) 2h=20
4) 2h/2=20/2
5) h=10

Let's solve your equation step-by-step.
7h−7=5h+13

Step 1: Subtract 5h from both sides.
7h−7−5h=5h+13−5h
2h−7=13

Step 2: Add 7 to both sides.
2h−7+7=13+7
2h=20

Step 3: Divide both sides by 2.
2h /2
=
20/ 2   h=10
