3X - 4 = 66
add 4 to each side
3X - 4 + 4 = 66 + 4
3X = 70
divide each sides integers by 3
(3/3)X = 70/3
X = 70/3
------------------check in original equation
3(70/3) - 4 = 66
210/3 - 4 = 66
70 - 4 = 66
66 = 66
---------------checks ( naturally, you could have canceled here, 3(70/3) and just got 70 )
