    no it is - 20 so we have 5a - 20 - 8a = 55 now combine the terms in a what is 5a - 8a ?

    no 13a is 5a + 8a 8a is greater than 5a so the answer is negative 5a - 8a = ?

    so we have -3a - 20 -= 55 now add 20 to both sides -3a - 20 + 20 = 55 + 20 the 20's cancel out -3a = 75 divide both sides by -3:- a = 75 / -3
