Solve x: 4 - 4x = 40 --Please Help! This is homework due in for Monday! Xx

salantis [7]

Hello!

Answer: x=-9 *The answer must have negative sign*

Explanation:

First you had to do is subtract by 4 from both sides of an equation.

$4-4x-4=40-4$

Then, simplify.

$-4x=36$

Divide by -4 both sides of an equation.

$\frac{-4x}{-4}= \frac{36}{-4}$

Finally simplify.

$36/4=9$

It change positive to negative sign.

$x=-9$

Hope this helps!

Thanks!

Have a great day!
