Question

Solve for x
-2^2(-5x+10)=100

Answer 1

`x=7`

Explanation:

Hi there!

`-2^2(-5x+10)=100`

Solve -2^2:

`-4(-5x+10)=100`

Divide both sides by -4:

`\displaystyle ( -4(-5x+10))/(-4)=(100)/(-4) \\\\-5x+10=-25`

Subtract 10 from both sides:

`-5x+10-10=-25-10\\-5x=-35`

Divide both sides by -5:

`\displaystyle (-5x)/(-5) = (-35)/(-5) \\\\x=7`

Therefore, x = 7.

I hope this helps!
