Solution for r-s=tr equation:


Simplifying
r + -1s = tr

Solving
r + -1s = rt

Solving for variable 'r'.

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

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

Combine like terms: rt + -1rt = 0
r + -1rt + -1s = 0

Add 's' to each side of the equation.
r + -1rt + -1s + s = 0 + s

Combine like terms: -1s + s = 0
r + -1rt + 0 = 0 + s
r + -1rt = 0 + s
Remove the zero:
r + -1rt = s

Combine like terms: s + -1s = 0
r + -1rt + -1s = 0
