To solve the equation \( 5(2x - 8) = -30 \), follow these steps:
-
Distribute the 5 on the left side of the equation: \[ 10x - 40 = -30 \]
-
Add 40 to both sides to isolate the term with \( x \): \[ 10x = -30 + 40 \] \[ 10x = 10 \]
-
Divide both sides by 10 to solve for \( x \): \[ x = \frac{10}{10} = 1 \]
So, the solution is: \[ \boxed{1} \]
