Answer:
S = -32
Explanation:
-5(s - 30) = -10
First distribute -5 to everything in the parenthesis.
-5 * s = -5s
-5 * - 30 = 150
What you have left is -5s + 150 = -10
Subtract 150 from both sides.
-5s + 150 - 150
Both 150's cancel each other out on the left side.
-10 - 150 = -160
What you're left with is -5s = -160
Divide both sides by -5 to get S by itself.
-5s / 5
The 5's cancel each other out on the left side.
-160 / 5 = -32
What you have left is S = - 32
