Studdy Solution

STEP 1

1. The equation −4=s−1 -4 = s - 1 is asking us to solve for s s .
2. This is a one-step equation with one solution.
3. The equation involves basic algebraic operations, specifically addition.

STEP 2

1. Understand the structure of the equation.
2. Isolate the variable s s by performing algebraic operations.
3. Check the solution by substituting it back into the original equation.

STEP 3

The equation −4=s−1 -4 = s - 1 indicates that s s minus 1 equals −4-4.

STEP 4

To isolate s s , we need to perform the opposite operation of subtraction, which is addition. Add 1 to both sides of the equation:
−4+1=s−1+1 -4 + 1 = s - 1 + 1

STEP 5

Simplify both sides of the equation:
−3=s -3 = s
or equivalently,
s=−3 s = -3

STEP 6

Check the solution by substituting s=−3 s = -3 back into the original equation:
−4=(−3)−1 -4 = (-3) - 1

STEP 7

Simplify the right-hand side:
−4=−4 -4 = -4
Both sides are equal, confirming that the solution is correct.
Therefore, the solution is:
−3 \boxed{-3}
