1. 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
