Answer:
- Add 9.6 to both sides of the equation
- Divide both side by the coefficient of x i.e 3.2
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
