9(x+2)=9

Answer 1

Respuesta:

x = -1

Explicación paso a paso:

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

First, divide 9 from both sides.

(9(x + 2))/9 = (9)/9

x + 2 = 9/9

x + 2 = 1

Isolate the variable x. Subtract 2 from both sides.

x + 2 (-2) = 1 (-2)

x = 1 - 2

x = -1

-1 is your answer for x.
