Question

Solve the following equations
a. 3n + 7 = 5

b. 8 - 2p = 10​

Answer 1

Answer:

a

3n +7=5

3n = 5-7

n = -2/3

b .

8-2p=10

-2p=10-8

-2p=2

-p = 2/2

p= -1

hence

n = -2/3

p = -1

Answer 2

Answer:

a. -2/3

b. -1

Step-by-step explanation:

a. 3n + 7 = 5

3n = 5 - 7

3n = -2

n = -2/3

b. 8 - 2p = 10

- 2p = 10 - 8

- 2p = 2

p = 2/-2 = 1/-1

p = -1
