Question

4(PX+1)=64 what is the value of x in terms of p and what is the value of x when p is -5 ?

Answer 1

x = -3

Explanation:

`4(PX+1)=64\\\\p= -5`

Substitute -5 for p in the given equation and solve

`4(-5(x)+1)=64\\\\\mathrm{Divide\:both\:sides\:by\:}4\\(4\left(-5x+1\right))/(4)=(64)/(4)\\\\Simplify\\-5x+1=16\\\\\mathrm{Subtract\:}1\mathrm{\:from\:both\:sides}\\-5x+1-1=16-1\\\\Simplify\\-5x =15\\\\\mathrm{Divide\:both\:sides\:by\:}-5\\(-5x)/(-5)=(15)/(-5)\\\\Simplify\\x = -3`
