L = w + 3L W = 28(w + 3) W = 28w2 + 3w = 28w2 + 3w - 28 = 0(w + 7) (w - 4) = 0w = -7 and W = 4L = 7
w > -2
4 - w = 7 subtract 4 from each side 4 - 4 - W = 7 - 4 - W = 3 divide both sides by - 1 ( remember, the implied coefficient of w is - 1 ) (- 1/- 1)w = 3/- 1 w = - 3 =======check in original equation 4 - (- 3) = 7 4 + 3 = 7 7 = 7 ========checks
