Which step can be done to both sides of the equation to determine the value of x?

3.2x - 9.6 = 38.4

Answer :

Answer:

Add 9.6 to both sides and then divide both sides by 3.2

Step-by-step explanation:

To solve for x in the equation 3.2x - 9.6 = 38.4, we should add 9.6 to both sides and then divide by 3.2, resulting in x = 15.

To determine the value of x in the equation 3.2x - 9.6 = 38.4, we need to perform the same mathematical operation on both sides of the equation. The steps involved are:

Add 9.6 to both sides to isolate the term with x on one side: 3.2x = 38.4 + 9.6.

After adding, simplify the right side of the equation: 3.2x = 48.

Divide both sides by 3.2 to solve for x: x = 48 / 3.2.

Simplify the right side to find the value of x: x = 15.

Therefore, the value of x is 15.
