What is the first step needed to solve (3/4)x - 3 = 18
Select one:
a. Add 3 to both sides
b. Subtract 18 from both sides
c. Multiply both sides by 3
d. Divide both sides by 4

Add 3 to both sides.

            18  

Step-by-step explanation:

To be able to find the answer to the given problem, we must plug in each answer choice to figure out which one works with the equation.

First, A. x = 2 , y = -7.

5(2)-(-7) = -3
10+7=-3
17=-3 (Nope!)

Next, B. x = 1, y = 2.

5(1) - (2) = -3
5 - 2 = -3
3 = -3 (Close, but opposite!)

Now, C. x = -2, y = 7.

5(-2) - (7) = -3
-10 - 7 = -3
-17 = -3 (Huh uh.)

Honestly now, do we need to go further?
Of course, we do! Just in case we messed up on one of the above answers and need to fix a mistake.

Last choice, D, x = -2, y = -7.

5(-2) - (-7) = -3
-10 + 7 = -3
-3 = -3 (Oh, snap! Found it.)

The correct answer is D, (-2, -7)!
