Solve equation.
-5(s-7) = 15
-5(s-7) = 15
-5s + 35 = 15
-5s = 15 - 35
-5s = - 20
s = 4
To solve the equation -5(s-7) = 15, we need to follow a series of steps. Here's how you can solve it:
Step 1: Distribute -5 to the terms inside the parentheses:
-5 * s = -5s
-5 * -7 = 35
So the equation becomes -5s + 35 = 15.
Step 2: Subtract 35 from both sides of the equation to isolate the term with -5s:
-5s + 35 - 35 = 15 - 35
-5s = -20.
Step 3: Divide both sides of the equation by -5 to solve for s:
(-5s) / -5 = (-20) / -5
s = 4.
Thus, the solution to the equation -5(s-7) = 15 is s = 4.
