65 = 3/4c - 7....add 7 to both sides 65 + 7 = 3/4c...simplify 72 = 3/4c...multiply both sides by 4/3, eliminating the 3/4 on the left 72 4/3 = c 288/3 = c 96 = c
36. -5/2 = 3/4z + 1/2 ...subtract 1/2 from both sides -5/2 - 1/2 = 3/4z .... simplify -6/2 = 3/4z ....reduce -3 = 3/4z....multiply by 4/3. eliminating the 3/4 on the left -3 4/3 = z -12/3 = z -4 = z
