4x-3 = 13
i have no clue how to do this

x = 4

Step-by-step explanation:

You are solving for the variable. Isolate the variable, x.

Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS:

PEMDAS =

Parenthesis

Exponents (& Roots)

Multiplication

Division

Addition

Subtraction

& is the order of operation in which you follow.

Solve:

First, add 3 to both sides:

4x - 3 = 13

4x - 3 (+3) = 13 (+3)

4x = 13 + 3

4x = 16

Next, to fully isolate the variable, x, divide 4 from both sides:

(4x)/4 = (16)/4

x = 16/4

x = 4

x = 4 is your answer.
