Obviously, a=3 To show... Simultaneously subtract the smaller variable on the right side (7a) from both sides and the lesser constant on the left side (-9) from both sides (subtracting a negative means to add a positive), or in other words... Subtract 7a from and add 9 to both sides to instantly force the value of 'a'... (1)a = 3 There, you have your answer... a=3
