h = 63

Explanation:

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation:
#h/9-7=0#
Rewrite the whole as a fraction using 9 as the denominator: #7=1/7=(7*9)/9#
Add the two equivalent fractions which now have a common denominator:
#(h-7*9)/9#
Simplified:
#(h-63)/9=0#
Where a fraction equals zero, its numerator must equal zero.
To get rid of the denominator, multiply both sides of the equation by the denominator. # (h-63)/9* 9 = 0 * 9 #
9 is canceled.
#h-63 = 0#
Add 63 on both sides:
#h-63+63=0+63#
Solution:
#h=63#
