You'll have to write it out using the drawing button first.

hero · Answer

Because it can be interpreted two ways:

$$2x + \frac{1}{3} - 2 = -7$$ or

$$\frac{2x+1}{3} - 2 = -7$$

In order to avoid ambiguity, most people use parentheses:

((2x+1)/3) - 2 = -7

Well I kind of needed someone to explain the whole problem to me because I am trying to prep for my SAT test, but thank you for the answer.

Hero, would you be able to explain it to me?

All you have to do is perform algebraic manipulation

1. Add 2 to both sides
2. Multiply both sides by 3
3. Subtract 1 from both sides
4. Divide both sides by 2
