Which steps can be done to both sides of the equation to determine the value of x ?
3.2x – 9.6 = 38.4

Step-by-step explanation:

The first step that can be done to both of the equation given is to add 9.6 to both sides of the equation as shown;

3.2x – 9.6 = 38.4

3.2x – 9.6+9.6 = 38.4+9.6

3.2x  = 38.4+9.6

3.2x = 48.0

step 2;

Divide both side by the coefficient of x i.e 3.2

3.2x/3.2 = 48.0/3.2

x = 15

Therefore the value of x is 15
