1. Copy the following and solve:
8÷4 X 9 + [-7- (53+9) + 6] X 32

2. 1. 6r + 7 = r
r = -6

3. x = 1 - x
x = 4

4. x – 3x + 2= -8x - 8
x = 5

5. b + 7 – 2b= 1 + 5b
b = -8

6. 5. n – 3n = 14 – 4n
n = 7

7. x = 2x + 6
No Solution

8. – 4x = -5 – 5(1 + 5x)
x = 1

9. Infinite Solutions (Identity)
x + 4(4x – 3) = 4(6x - 4) + 4
Infinite Solutions (Identity)

10. n – 20 = -2n + 4(1 – 3n)
n = 3

11. 5 6 1 2 2 3
10. x + = x + 4
x = 21

12. 11. The number of girls in the band is 6 more than twice the number of boys. There are 88 girls in the band. How many boys are there?
2b + 6 = 88
b = 41

13. 2x + 4 = 3x – 4 4
x = 2
