11,3x+7,2=86,3
⇔11,3x=86,3-7,2=79,1
⇔x=79,1/11,3= 7

The answers is c) 7 :).

Answer 2

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.
