2(s-t)=2s-2t

Solution for 2(s-t)=2s-2t equation:

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

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

Combine like terms: 2s + -2s = 0
0 + -2t = 2s + -2s + -2t
-2t = 2s + -2s + -2t

Combine like terms: 2s + -2s = 0
-2t = 0 + -2t
-2t = -2t

Add '2t' to each side of the equation.
-2t + 2t = -2t + 2t

Combine like terms: -2t + 2t = 0
0 = -2t + 2t

Combine like terms: -2t + 2t = 0
0 = 0
