Solution for S(r+t)=rat equation:


Simplifying
S(r + t) = rat
(r * S + t * S) = rat
(rS + tS) = rat

Solving
rS + tS = art

Solving for variable 'r'.

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

Add '-1art' to each side of the equation.
rS + -1art + tS = art + -1art

Reorder the terms:
-1art + rS + tS = art + -1art

Combine like terms: art + -1art = 0
-1art + rS + tS = 0

Add '-1tS' to each side of the equation.
-1art + rS + tS + -1tS = 0 + -1tS

Combine like terms: tS + -1tS = 0
-1art + rS + 0 = 0 + -1tS
-1art + rS = 0 + -1tS
Remove the zero:
-1art + rS = -1tS

Combine like terms: -1tS + tS = 0
-1art + rS + tS = 0
