Answer (3)

Calculate them all. a)16x+5(2x+8)-14=16x+10x+40-14=26+26x b)26-2(3x)=26-6x c)6x-28+10(x+4)-14=6x-28+10x+40-14=16x-2 d)26-6x There are two equivalent ones, which give no real majority...

The expression that is not equivalent to the others is C: − 12 x + 26 because it results in a different coefficient for x compared to the other options. Options A, B, and D all simplify to the same value. Thus, C is the correct answer.
