To solve for x, we need to use the distributive property to expand the expression on the left side of the equation before simplifying it.
20x - 5(6x + 15) = -45
20x - 30x - 75 = -45
-10x - 75 = -45
Next, add 75 to both sides of the equation to isolate the variable term:
-10x = -45 + 75
-10x = 30
Now, divide by -10 to solve for x:
x = 30 / -10
x = -3
Therefore, the solution to the equation is x = -3.
20x - 5(6x + 15) = -45
20x - 30x - 75 = -45
-10x - 75 = -45
Next, add 75 to both sides of the equation to isolate the variable term:
-10x = -45 + 75
-10x = 30
Now, divide by -10 to solve for x:
x = 30 / -10
x = -3
Therefore, the solution to the equation is x = -3.
