l = 3w-2 When a problem says "less than" (not "is less than"), you should put the minus sign BEFORE the number. p = 60 The formula of perimeter is 2l + 2w 60 = 2l + 2w Replace the l with the formula of l. 60 = 2(3w-2)+2w Solve the problem: Distribute 60 = 6w-4+2w Combine lile terms 60 = 8w-4 64=8w Divide w=8
