Step-by-step explanation:
Simplifying
3x + -1s = r
Reorder the terms:
-1s + 3x = r
Solving
-1s + 3x = r
Solving for variable 's'.
Move all terms containing s to the left, all other terms to the right.
Add '-3x' to each side of the equation.
-1s + 3x + -3x = r + -3x
Combine like terms: 3x + -3x = 0
-1s + 0 = r + -3x
-1s = r + -3x
Divide each side by '-1'.
s = -1r + 3x
Simplifying
s = -1r + 3x
