x=2

Answer 2

x = 2

Explanation:

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,

and is the order in which you follow for order of operation questions.

First, subtract 5 from both sides.

2x + 5 (-5) = 9 (-5)

2x = 9 - 5

2x = 4

Isolate the x, Divide 2 from both sides:

(2x)/2 = (4)/2

x = 4/2

x = 2

x = 2 is your answer.
