Answer: x=7

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

−(12+4x)=−40

−4x+−12=−40(Distribute)

−4x−12=−40

Step 2: Add 12 to both sides.

−4x−12+12=−40+12

−4x=−28

Step 3: Divide both sides by -4.

−4x

−4

−28

−4

Serga [27]

(-∞,4). All I did was isolated x, and it says that x has to be less than 4. That means anything before 4 is fair game. Since the problem said that it can't be equal to 4 (as it would have had to have a line under the less than symbol), I used parenthesis on the 4 side as opposed to hard brackets. The ∞ always requires parenthesis.
