Type the correct answer in each box.

4(px+1)=64

The value of x in terms of p is

The value of x when p is −5 is

Answer 1

x =
`(15)/(p)`

x(p is - 5) = -3

Explanation:

In order to solve for 'x' in the equation, we need to use inverse operations. We use opposite operations to get rid of the terms connected to the variable and whatever we do to one side of the equation, we do to the other. First, divide both sides by 4:

`(4(px +1))/(4) =(64)/(4)`

px +1 = 16, now subtract '1' from both sides: px +1 - 1 = 16 - 1

px = 15, now divide both sides by 'p':
`(px)/(p) =(15)/(p)`

When p = -5, then we can find the value of x:
`(15)/(-5) = -3`
