-2x+14=20 x=-3

I am having difficulty understanding your question. 12 + 20 = 10 is obviously false (12 + 20 = 32).If 4x + 14 = 2x + 30, then x must equal 8.
-2x-6 = 14 -2x = 14+6 -2x = 20 x = -10
4x + 2 + 2x - 2x = 14 4x = 14 - 2 4x = 12 x = 3
The slope will be the same but the y intercept will change:- y -14 = - 2(x - 10) y -14 = -2x +20 y = -2x +20 +14 y = -2x +34
2x + 5y = 16 -2x - 3y = -14 2y = 2 y = 1 / x = 5.5 (5.5,1) or (5 1/2,1)
