Answer:

x = 9

Step-by-step explanation:

Isolate the variable, x. Note the equal sign, what you do to one side of the equation, you do to the other. Do the opposite of PEMDAS.

PEMDAS is the order of operations, and stands for:

Parenthesis

Exponents (& Roots0

Multiplications

Divisions

Additions

Subtractions

~

First, add 2 to both sides of the equation:

[tex]2x - 2 = 16\\2x - 2 (+2) = 16 (+2)\\2x = 16 + 2\\2x = 18[/tex]

Next, divide 2 from both sides of the equation:

[tex]2x = 18\\\frac{(2x)}{2} = \frac{18}{2}\\ x = \frac{18}{2}\\x = 9[/tex]

~

x = 9 would be your answer.
