To solve this equation, we will first distribute the -4 to the terms inside the parentheses:
-12x - 40 - 2 = 54
Next, we combine like terms:
-12x - 42 = 54
To isolate the variable, we will add 42 to both sides:
-12x = 54 + 42
-12x = 96
Finally, we divide both sides by -12 to solve for x:
x = 96 / -12
x = -8
Therefore, x = -8.

x=?
To solve this equation, we will first distribute the -5 to the terms inside the parentheses:
20x - 5(6x+15) = -45
20x - 30x - 75 = -45
Next, we combine like terms:
-10x - 75 = -45
To isolate the variable, we will add 75 to both sides:
-10x = -45 + 75
-10x = 30
Finally, we divide both sides by -10 to solve for x:
x = 30 / -10
x = -3
Therefore, x = -3.
20x - 5(6x+15) = -45
20x - 30x - 75 = -45
Next, we combine like terms:
-10x - 75 = -45
To isolate the variable, we will add 75 to both sides:
-10x = -45 + 75
-10x = 30
Finally, we divide both sides by -10 to solve for x:
x = 30 / -10
x = -3
Therefore, x = -3.
