Answer 26

There are a couple of ways to do this...

3/4z - 1/6 = - 1/2......to get rid of fractions, multiply everything by the common denominator of 12
(12)3/4z - (12)1/6 = (12) - 1/2
9z - 2 = - 6 --- add 2 to both sides
9z = -6 + 2
9z = -4
z = -4/9

OR THIS WAY
3/4z - 1/6 = -1/2 --- add 1/6 to both sides
3/4z = -1/2 + 1/6
3/4z = - 3/6 + 1/6
3/4z = -2/6 -- divide both sides by 3/4
z = (-2/6) / (3/4)
z = -2/6 * 4/3
z = - 8/18 which reduces to - 4/9
