To solve for x, we need to simplify the equation and then isolate x.
First, we will distribute the -5 to the terms inside the parentheses: -5(6x + 15) = -30x - 75
Now, we can rewrite the equation: 20x - 30x - 75 = -45
Combine like terms: -10x - 75 = -45
Next, we will isolate x by moving -75 to the opposite side of the equation:
Add 75 to both sides: -10x = -45 + 75
Simplify: -10x = 30
To solve for x, divide both sides by -10:
x = 30 / -10
Simplify: x = -3
Therefore, the solution to the equation is x = -3.
