Answer:

The first operation is to add, and you are adding 3 to both sides of the equation to isolate the x.

Explanation:

Note the equal sign, what you do to one side, you do to the other. You are solving for the variable, x, when solving this equation.

Remember to do the opposite of PEMDAS. PEMDAS is the order of operation, and stands for:

Parenthesis

Exponents (& Roots)

Multiplication

Division

Addition

Subtraction

The first step is to add 3 to both sides of the equation:

(x/3) - 3 (+3) = 11 (+3)

(x/3) = 11 + 3

(x/3) = 14

The second step is to multiply 3 to both sides of the equation:

(x/3) * 3 = (14) * 3

x = 14 * 3

x = 42

42 would be your final answer.
