t(2-m)+s(2-m)=0

Solution for t(2-m)+s(2-m)=0 equation:

Simplifying
t(2 + -1m) + s(2 + -1m) = 0
(2 * t + -1m * t) + s(2 + -1m) = 0

Reorder the terms:
(-1mt + 2t) + s(2 + -1m) = 0
(-1mt + 2t) + s(2 + -1m) = 0
-1mt + 2t + (2 * s + -1m * s) = 0

Reorder the terms:
-1mt + 2t + (-1ms + 2s) = 0
-1mt + 2t + (-1ms + 2s) = 0

Reorder the terms:
-1ms + -1mt + 2s + 2t = 0

Solving
-1ms + -1mt + 2s + 2t = 0

Solving for variable 'm'.

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

Add '-2s' to each side of the equation.
-1ms + -1mt + 2s + -2s + 2t = 0 + -2s

Combine like terms: 2s + -2s = 0
-1ms + -1mt + 0 + 2t = 0 + -2s
-1ms + -1mt + 2t = 0 + -2s
Remove the zero:
-1ms + -1mt + 2t = -2s

Add '-2t' to each side of the equation.
-1ms + -1mt + 2t + -2t = -2s + -2t

Combine like terms: 2t + -2t = 0
-1ms + -1mt + 0 = -2s + -2t
-1ms + -1mt = -2s + -2t

Reorder the terms:
-1ms + -1mt + 2s + 2t = -2s + 2s + -2t + 2t

Combine like terms: -2s + 2s = 0
-1ms + -1mt + 2s + 2t = 0 + -2t + 2t
-1ms + -1mt + 2s + 2t = -2t + 2t

Combine like terms: -2t + 2t = 0
-1ms + -1mt + 2s + 2t = 0
