WILL MEDAL AND FAN

John is trying to solve the following equation.

1/3 (8x + 9) = 2x

Explain and justify the first step John could use to solve the equation.

Answer 1

Choices!

A. John could divide the 8x by 3 to eliminate the need for the set of parenthesis.

B. John could subtract 2x from the right side of the equation in order to combine like terms.

C. John could subtract 9 from the right side of the equation to isolate the variable on the left side.

D. John could multiply each side of the equation by 3 to keep the equation balanced and to simplify the equation.

Answer 2

I don't think it is C because the 9 is in parenthesis.

I am sort of leaning towards D, but I am not sure.

Answer 3

I think you're correct.

Answer 4

We can divide 1/3 to both sides, which is the same thing as multiplying by 3.
