22 - 5(6v - 1) = 63 The most common error that would be likely to be made here would be to violate "PEMDAS" and do 22 - 5 first and get 17. That would be wrong. We must multiply first by distributing the -5 into the parentheses: 22 - 30v + 5 = 63 Combine the 22 and the +5, getting 27 27 - 30v = 63 Subtract 27 from both sides -30v = 36 Divide both sides by -30 v = 36/(-30) v = -36/30 v = -6/5 Edwin
