Question

5x + 2 = 12

Solve the following equation. Then place the correct number in the box provided.

Answer 1

x = 2

Explanation:

5x + 2 = 12

Subtract 2 from both sides

5x + 2 - 2 = 12 - 2

Simplifying

5x = 10

Divide both sides by 5

5x / 5 = 10/5

Simplifying

x = 2

Answer 2

x = 2

Explanation:

You are solving for the variable, x. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS, and isolate the variable.

First, subtract 2 from both sides.

5x + 2 = 12

5x + 2 (-2) = 12 (-2)

5x = 12 - 2

5x = 10

Isolate the variable, x. Divide 5 from both sides.

(5x)/5 = (10)/5

x = 10/5

x = 2

x = 2 is your answer.
