Answer:
one solution: h = 3
Step-by-step explanation:
The coefficients of h on either side of the equal sign are different, so there is one solution. (If they were the same, there might be 0 or infinite solutions.)
2(h +1) = 5h -7 . . . . given
2h +2 = 5h -7 . . . . eliminate parentheses
9 = 3h . . . . . . . . . . add 7-2h
3 = h . . . . . . . . . . . divide by 3
The solution is h = 3.
