Answer:

The correct option is C) 7.

Explanation:

Consider the provided equation.


11.3x+7.2=86.3

We need to solve the provided equation for x.

Subtract 7.2 from both side.


11.3x+7.2-7.2=86.3-7.2


11.3x=79.1

Divide both sides by 11.3.


(11.3x)/(11.3)=(79.1)/(11.3)


x=7

Hence, the value of the equation is x=7.

Thus the correct option is C) 7.
