To solve for s, we will first distribute the -30 to the terms inside the parentheses:
-30s + 300 = -180
Next, we will move the constant term to the right side of the equation by subtracting 300 from both sides:
-30s = -180 - 300
This simplifies to:
-30s = -480
To isolate s, we divide both sides of the equation by -30:
s = -480 / -30
This simplifies to:
s = 16
Therefore, s is equal to 16.
