Question

Solve the following equation
3n +7= 25
8t + 3 = 99
4 ( x + 3 ) = 26
6 ( p + 2 ) = - 18

Answer 1

Step-by-step explanation:

1. 3n + 7 = 25

3n = 25 - 7

3n = 18

n = 18 / 3

N = 6

2. 8t + 3 = 99

8t = 99 - 3

8t = 96

t = 96 / 8

t = 12

3. 4 ( x + 3 ) = 26

multiply 4 with ( x + 3 )

so, 4x + 12 = 26

4x = 26 -12

4x = 14

x = 14 / 4

x = 3.5

4. 6 ( p + 2 ) = - 18

multiplying 6 by ( p + 2 )

Then, 6p + 12 = -18

6p = - 18 - 12

6p = - 30

p = - 30 / 6

p = -5
