92 = -4(2r - 5) r = ? Help!

Roman55 [17]

Hello there!

$92 = -4(2r - 5)\\$

Explanation:

↓↓↓↓↓↓↓↓↓↓↓↓

First you had to switch sides.

$-4(2r-5)=92$

Then you divide by -4 from both sides of the equation.

$\frac{-4(2r-5)}{-4}=\frac{92}{-4}$

Simplify

$2r-5=-23$

Next you had to add by 5 from both sides of the equation.

$2r-5+5=-23+5$

Simplify

$2r=-18$

You can also divide by 2 from both sides of the equation.

$\frac{2r}{2}=\frac{-18}{2}$

Simplify it should be the correct answer.

$r=-9$

Answer⇒⇒⇒⇒⇒r=-9

Hope this helps!
