Answer:

-1 1/6

Explanation:

9 + x = 2 - 5x

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

Parenthesis

Exponents (& Roots)

Multiplication

Division

Addition

Subtraction

& is the order of operation.

Isolate the variable, x. Subtract x and 2 from both sides:

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

9 - 2 = -5x - x

7 = -6x.

Simplify. Isolate the variable, x. Divide -6 from both sides:

(7)/-6 = (-6x)/-6

x = - 7/6 = -1 1/6
