    12 (x - 2) - 10 (x + 7) = 14 (multiply through the parenthesis) 12x - 24 - 10x - 70 = 14 2x - 94 = 14 (add 94 to both sides to get 2x by itself) 2x - 94 + 94 = 14 + 94 2x = 108 (divide 2 on both sides to gey x by itself) 2x/2 = 108/2 x = 54 Check your answer ... Sub 54 in for x in the original equation.... 12(54 - 2) - 10(54 + 7) = 14 12(52) - 10(61) = 14 624 - 610 = 14 14 = 14 (correct)
