3n - 24 = 14 - 30n33n = 38n = 38/33

-96 = 33-y -96-33 = -y -129 = -y y = 129 Remember a minus divided into a minus is equal to a plus.

3x + 9 = 42 3x = 33 x = 11

x + 7y = 33 (1) --> x = 33 - 7y (1a) 3x - 2y = 7 (2) To solve the simultaneous equations, starts by substituting the value for x found in (1a) into (2): 3(33 - 7y) - 2y = 7 99 - 21y - 2y = 7 -23y = -92 y = 4 Now substitute this value for y into (1a) and solve for x: x = 33 - 7(4) x = 33 - 28 x = 5 Therefore these equations have the solution x = 5, y = 4
