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
