1) h/4 + 9 = 6
You want to isolate h by itself, so subtract both sides by 9.
h/4 = -3
Then, get rid of the denominator, 4, by multiplying both sides by 4 (nit a fraction but as awhole number)
h = -12
2) Apply the same concept to this problem.
m/-3 + (-2) = 11
Distribute the sign over the parenthesis.
m/-3 - 2 = 11
Add 2 to both sides.
m/-3 = 13
To get rid of the denominator, multiply both sides by -3
m = -39
3) r/-5 - (-6) = 10
r/-5 + 6 = 10
r/-5 = 4
r = -20
4) z/-4 + (-5) = -12
z/-4 - 5 = -12
z/-4 = -7
z = 28
5) t/-8 - (-4) = -6
t/-8 + 4 = -6
t/-8 = -10
t = 80
