Answer:
C. Both A & B
Step-by-step explanation:
Solve the equations given:
Equation A:
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, subtract 11x and add 7 to both sides:
16x (-11x) - 7 (+7) = 11x (-11x) - 32 (+7)
16x - 11x = -32 + 7
Simplify. Combine like terms:
16x - 11x = -32 + 7
5x = -25
Isolate the variable, x. Divide 5 from both sides:
(5x)/5 = (-25)/5
x = -25/5
x = -5
Equation A is an answer choice.
Equation B:
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, add 10 & subtract 2x from both sides:
-4x (-2x) - 10 (+10) = 2x (-2x) + 20 (+10)
-4x - 2x = 20 + 10
Simplify. Combine like terms:
-4x - 2x = 20 + 10
-6x = 30
Isolate the variable, x. Divide -6 from both sides:
(-6x)/-6 = (30)/-6
x = 30/-6
x = -5
Equation B is also an answer choice.
C. Both A & B is your answer.
