Answer 1

7) t=-13
1) p= -33
4) d= -99

Answer 2

Explanation:

1) - p/3 - 8 = 3

Adding 8 to the left hand side and the right hand side of the equation, it becomes

- p/3 - 8 - 8 = 3 - 8

- p/3 = - 5

Multiplying the left hand side and the right hand side of the equation by - 3, it becomes

- p/ 3 × - 3 = - 5 × - 3

p = 15

4) d/11 - 4 = - 13

Adding 4 to the left hand side and the right hand side of the equation, it becomes

d/11 - 4 + 4 = - 13 + 4

d/11 = - 9

Multiplying the left hand side and the right hand side of the equation by 11, it becomes

d/11 × 11 = - 9 × 11

d = - 99

7) 5t + 12 = 4t - 1

Subtracting 12 and 4t from

the left hand side and the right hand side of the equation, it becomes

5t - 4t + 12 - 2= 4t - 4t - 1 - 12

t = - 13
