Answer:

x = -2

Step-by-step explanation:

To solve, we need to <u>isolate "x"</u> by moving other numbers to the right side of the equal sign. To "move" a number, <u>do the reverse operation to both sides of the equation</u>. <u>Move numbers in reverse BEDMAS order</u>.

4(-2x - 1) = 12                Do the opposite of times 4

Divide both sides by 4

-2x - 1 = 3                     Do the opposite of subtract 1

Add 1 to both sides

-2x = 4                          Do the opposite of times -2

Divide both sides by -2

x = -2                         Solved for "x"
