Question

Find the value of the unknown in the equation 4p + 2 = 8

a) p = 0
b) p = 2.3
c) p = 1.5
d) p = 4

Answer 1

The answer is C.

Explanation:

First, you have to subtract 2 to both sides :

`4p + 2 = 8`

`4p + 2 - 2 = 8 - 2`

`4p = 6`

Next, you have to divide it by 4 :

`4p = 6`

`p = 6 / 4`

`p = 3 / 2`

`p = 1.5`

Answer 2

Option C

Explanation:

=> 4p + 2 = 8

Subtracting 2 to both sides

=> 4p = 8-2

=> 4p = 6

Dividing both sides by 4

=> p = 1.5
