# Simple Equations Module 1

## Keep up the good work.

### #1. h – 6 = 25

h – 6 = 25

h – 6 † 6 = 25 † 6

h = 31

### #2. b + 93 = 150

b † 93 = 150

b † 93 – 93 = 150 -93

b = 57

### #3. n - 42 = 50

n – 42 = 50

n – 42 † 42 = 50 † 42

n = 92

9f = 108

9f/9 = 108/9

f = 12

### #5. q - 3 = 33

q – 3 † 3 = 33 † 3

q = 36

### #6. p + 65 = 100

p † 65 = 100

Subtract 65 from both sides

p † 65 – 65 = 100 – 65

p = 35

### #7. c/5 = 18

c = 18

Multiply both sides by 5

c × 5 = 18 × 5

c = 90

### #8. d - 9 = 20

d – 9 = 20

d – 9 † 9 = 20 † 9

d = 29

### #9. 7.4 + j = 13.2

7.4 † j = 13.2

Subtract 7.4 from both sides

7.4 j – 7.4 = 13.2 – 7.4

j = 5.8

### #10. 5 + a = 17

5 † a = 17

Subtract 5 from both sides

5 † a – 5 = 17 – 5

a = 12

### #11. 15y = 300

15y = 300
Divide both sides by 15
15y/15 = 300/15
y = 20

### #12. 2w/5 = 8

2/5w = 8

Multiply both sides by 5

2/5w × 5 = 8 × 5

2w = 40

Divide both sides by 2

2w/2 = 40/2

w = 20

### #13. 11 – h = 4.5

11 – h = 4.5

11 – h † h = 4.5 † h

11 = 4.5 † h

Subtract 4.5 from both sides

11 – 4.5 = h

6.5 = h

### #14. c - 27 = 38

c – 27 = 38

c – 27 † 27 = 38 † 27

c = 65

### #15. b - 5 = 21

b – 5 † 5 = 21 † 5

b = 26

### #16. 3j/8 = 3

3/8j = 3
Multiply by 8
3/8j × 8 = 3 × 8
3j = 24
Divide both sides by 3
3j/3 = 24/3
j = 8

### #17. a + 6 = 26

a † 6 = 26

Subtract 6 from both sides

a † 6 – 6 = 26- 6

a = 20

### #18. m + 14 = 35

m † 14 = 35

Subtract 14 from both sides

m † 14 – 14 = 35 – 14

m = 21

### #19. f + 8 = 19

f † 8 = 19

Subtract 8 from both sides

f † 8 – 8 = 19 – 8

f = 11
