    Oh okay. so when we simplify this we get 6a +18 = 21 -3-1+2a right?

    Let's see. 6a +18 = 21 -3-1+2a simplify the right side 6a + 18 = 21-4 +2a simplify again 6a + 18 = 17 + 2a bring all the a's to one side of the equation 6a -2a +18 = 17 simplify left side 4a +18 = 17 bring all the numbers to the other side of the equation 4a = 17 - 18 simplify 4a = -1 isolate a on one side by dividing both sides of the equation by 4 4a/4 = -1/4 Simplify a = -1/4
