⇔11,3x=86,3-7,2=79,1
⇔x=79,1/11,3= 7

The answers is c) 7 :). 

Answer:

The correct option is C) 7.

Step-by-step explanation:

Consider the provided equation.

[tex]11.3x+7.2=86.3[/tex]

We need to solve the provided equation for x.

Subtract 7.2 from both side.  

[tex]11.3x+7.2-7.2=86.3-7.2[/tex]

[tex]11.3x=79.1[/tex]

Divide both sides by 11.3.

[tex]\frac{11.3x}{11.3}=\frac{79.1}{11.3}[/tex]

[tex]x=7[/tex]

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

Thus the correct option is C) 7.
