Solution for s(r+t)=rt equation:


Simplifying
s(r + t) = rt
(r * s + t * s) = rt
(rs + st) = rt

Solving
rs + st = 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.
rs + -1rt + st = rt + -1rt

Combine like terms: rt + -1rt = 0
rs + -1rt + st = 0

Add '-1st' to each side of the equation.
rs + -1rt + st + -1st = 0 + -1st

Combine like terms: st + -1st = 0
rs + -1rt + 0 = 0 + -1st
rs + -1rt = 0 + -1st
Remove the zero:
rs + -1rt = -1st

Combine like terms: -1st + st = 0
rs + -1rt + st = 0
