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 )
68 - 56 is 12 plus 54 is 66 plus 66 is 132.
