S(r-3)=

Solution for S(r-3)= equation:

Simplifying
S(r + -3) = 0

Reorder the terms:
S(-3 + r) = 0
(-3 * S + r * S) = 0
(-3S + rS) = 0

Solving
-3S + rS = 0

Solving for variable 'S'.

Move all terms containing S to the left, all other terms to the right.

Factor out the Greatest Common Factor (GCF), 'S'.
S(-3 + r) = 0

Subproblem 1
Set the factor 'S' equal to zero and attempt to solve:

Simplifying
S = 0

Solving
S = 0

Move all terms containing S to the left, all other terms to the right.

Simplifying
S = 0
Subproblem 2
Set the factor '(-3 + r)' equal to zero and attempt to solve:

Simplifying
-3 + r = 0

Solving
-3 + r = 0

Move all terms containing S to the left, all other terms to the right.

Add '3' to each side of the equation.
-3 + 3 + r = 0 + 3

Combine like terms: -3 + 3 = 0
0 + r = 0 + 3
r = 0 + 3

Combine like terms: 0 + 3 = 3
r = 3

Add '-1r' to each side of the equation.
r + -1r = 3 + -1r

Combine like terms: r + -1r = 0
0 = 3 + -1r

Simplifying
0 = 3 + -1r
