Question

4(px+1)=64The value of x when p is -5 is ?

Answer 1

x = -3

Step-by-step explanation:

Given the equation:

`4\left(px+1\right)=64`

We are required to find the value of x when p is -5.

`\begin{gathered} 4\left(px+1\right)=64\colon p=-5 \\ 4\left(-5x+1\right)=64 \\ -20x+4=64 \\ -20x=64-4 \\ -20x=60 \\ \text{Divide both sides by -20} \\ x=(60)/(-20) \\ x=-3 \end{gathered}`
