Question

Jason is given the equation 3x − 12 = 36 to solve. His first step is to divide each term by 3. Do you think Jason's method is a good one to follow? Give an example to help justify your answer

Answer 1

It works and is a good one to follow if each term is divisible by the same number!

Explanation:

Dividing each term by 3 will give us the equation x - 4 = 12 which leads to the correct answer of x = 16.

However, if there each term is not divisible by the same number, it is not a good method to follow (because it will not work).

Answer 2

No, Jason's method is not a good one to follow, because u have to let x alone, and try to break down the constant.

Explanation:

Jason should do 3x - 12 = 36

3x + 12 = + 12

3x = 48

x = 16
