Solve for h.

6.51 - 9.32 + h = 1.02

If you subtract 6.51-9.32 that gets you - 2.81+h=1.02, then add - 2.81 on both side so you eliminate the negative number on the left and the number on the right becomes 3.83 Which is what h equals

If you 6.51 - 9.32 you would get - 2.81 or somewhere close to that and then you're going to add it to both sides which makes it 3.83
