9s+20=-16

Answer 1

To solve for s, we need to isolate the variable on one side of the equation.

To do this, we can start by subtracting 20 from both sides of the equation:

9s + 20 - 20 = -16 - 20

This simplifies to:

9s = -36

To solve for s, divide both sides of the equation by 9:

9s / 9 = -36 / 9

This simplifies to:

s = -4

Therefore, the solution is s = -4.
