What value of x makes the equation true?

Aleksandr [31]

♥ Answer: x=-6.9

Solve:
You need to Simplify both sides of the equation.
 $806.265=-116.85x$
Now: Flip the equation.
 $-116.85x=806.265$ 
Lastly Divide both sides by -116.85.
 $\frac{-116.85x}{-116.85} = \frac{806.265}{-116.85}$

Final answer: x=-6.9
