# How do you simplify 15p - 20= 4p - 64?

Jun 7, 2018

$p = - 4$

#### Explanation:

$\text{to solve the equation collect terms in p on the left}$
$\text{side of the equation and numeric values on the right side}$

$\text{subtract "4p" from both sides}$

$15 p - 4 p - 20 = - 64$

$11 p - 20 = - 64$

$\text{add 20 to both sides}$

$11 p = - 64 + 20 = - 44$

$\text{divide both sides by 11}$

$\frac{\cancel{11} p}{\cancel{11}} = \frac{- 44}{11} \Rightarrow p = - 4$

Isolate the variable.

#### Explanation:

Put the coefficients on one side of the equal sign and the constants on the other side (subtract $15 p$ on both sides and add $64$ on both sides).

You will get

$- 11 p = 44.$

Divide by $- 11$ on both sides then you will get the solution:

$p = - 4$
