Answer 2

Answer:

The correct option is C) 7.

Step-by-step 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.

$\frac{11.3x}{11.3}=\frac{79.1}{11.3}$

$x=7$

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

Thus the correct option is C) 7.
