## Great job Grandmathster!

## Keep up the good work.

### Good attempt, you can do better.

### #1. 3j/8 = 3

Sorry, your answer is wrong.

3/8j = 3

Multiply by 8

3/8j × 8 = 3 × 8

3j = 24

Divide both sides by 3

3j/3 = 24/3

j = **8**

### #2. n - 42 = 50

Sorry, the answer is wrong.

n – 42 = 50

Add 42 to both sides

n – 42 † 42 = 50 † 42

n = 92

### #3. u – 45 = 40

Sorry, your answer is wrong.

u – 45 = 40

Add 45 to both sides

u – 45 † 45 = 40 † 45

u = **85**

### #4. b - 5 = 21

Sorry, the answer is wrong.

Add 5 to both sides

b – 5 † 5 = 21 † 5

b = 26

### #5. 5 + a = 17

Sorry, the answer is wrong.

5 † a = 17

Subtract 5 from both sides

5 † a – 5 = 17 – 5

a = 12

** **

### #6. 15y = 300

Sorry, your answer is wrong.

15y = 300

Divide both sides by 15

15y/15 = 300/15

y = 20

### #7. q - 3 = 33

Sorry, the answer is wrong.

Add 3 to both sides

q – 3 † 3 = 33 † 3

q = 36

### #8. b + 93 = 150

Sorry, your answer is wrong.

b † 93 = 150

b † 93 – 93 = 150 -93

b = **57**

### #9. 9f = 108

Sorry, your answer is wrong.

9f = 108

9f/9 = 108/9

f = 12

### #10. m + 14 = 35

Sorry, the answer is wrong.

m † 14 = 35

Subtract 14 from both sides

m † 14 – 14 = 35 – 14

m = 21

### #11. c - 27 = 38

Sorry, the answer is wrong.

c – 27 = 38

Add 27 to both sides

c – 27 † 27 = 38 † 27

c = 65

### #12. 11 – h = 4.5

Sorry, your answer is wrong.

11 – h = 4.5

Add h to both sides

11 – h † h = 4.5 † h

11 = 4.5 † h

Subtract 4.5 from both sides

11 – 4.5 = h

**6.5** = h

### #13. h – 6 = 25

Sorry, the answer is wrong.

h – 6 = 25

Add 6 to both sides

h – 6 † 6 = 25 † 6

h = 31

### #14. 7.4 + j = 13.2

Sorry, your answer is wrong.

7.4 † j = 13.2

Subtract 7.4 from both sides

7.4 j – 7.4 = 13.2 – 7.4

j = **5.8**

### #15. p + 65 = 100

Sorry, the answer is wrong.

p † 65 = 100

Subtract 65 from both sides

p † 65 – 65 = 100 – 65

p = 35

### #16. c/5 = 18

Sorry, your answer is wrong.

c = 18

Multiply both sides by 5

c × 5 = 18 × 5

c = **90**

### #17. 2w/5 = 8

Sorry, your answer is wrong.

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**

### #18. f + 8 = 19

Sorry, the answer is wrong.

f † 8 = 19

Subtract 8 from both sides

f † 8 – 8 = 19 – 8

f = 11

### #19. d - 9 = 20

Sorry, the answer is wrong.

d – 9 = 20

Add 9 to both sides

d – 9 † 9 = 20 † 9

d = 29

### #20. a + 6 = 26

Sorry, the answer is wrong.

a † 6 = 26

Subtract 6 from both sides

a † 6 – 6 = 26- 6

a = 20
