STALIN [3.7K]

Answer:

x = 2

Step-by-step 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.

PEMDAS is the order of operation, and =

Parenthesis

Exponents (& Roots)

Multiplication

Division

Addition

Subtraction.

First, subtract 25 from both sides of the equation:

5x + 25 (-25) = 35 (-25)

5x = 35 - 25

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.
