$3 / 4f +5 / 2 = 4f - 8\\0.75f - 4f = - 8 - 2.5\\3.25f = - 10.5\\f = - 10.5 / 3.25\\f = - 3.23076\\\\12m - 5m = - 7 - 6\\7m = - 13\\m = - 13 / 7\\m = 1.85714\\\\5x - 2x = 1 - 8 + 4\\3x = - 3\\x = - 3 / 3\\x = - 1\\15r - 6 - 1 = 6 - 8r + 8\\15r + 8r = 6 + 8 +6 + 1\\23r = 21\\r = 21 / 23\\r = 0.1304\\\\2s + 1 / 3 = 5s - 9\\2s / 1 - 5s / 1 = - 9 - 1 / 3\\- 3s = - 9 - 1 / 3\\- 3s = - 9.33333\\s = - 9.33333 / - 3\\s = 3.11111$
