**SOLVING EQUATIONS AND EXPANDING BRACKETS**

2
**AIM: USE FLOWCHARTS TO SOLVE EQUATIONS**

3
6B – 5 = 13 B 6 -5 13 B 6 +5 13 B = 3 NOW TRY THESE 1. A + 10 = B – 4 = 20 6C = A + 7 = 25 5. 5Y – 1 = V + 3 = 37

4
AIM: EXPAND BRACKETS 3(A + 5) This means the same as A + 5 A + 5 A + 5 3A + 15 Can you see a quick way of doing this? 7(B + 3) = 7B + 21 5(y - 4) = 5y - 20 3(2c + 5) = 6c + 15

5
**AIM: EXPAND BRACKETS AND SOLVE THE EQUATION**

EXPANDED 5A + 10 = 30 FLOWCHART A 5 +10 30 A 5 -10 30 A = 4
