Which equations have equivalent expressions? check all that are true. a. 2t + 3t = 6t b. y + y + y = y(1 + 1 + 1) c. 3(2 + x) = 6 + 3x d. 2a + 2b = 4ab e. x + 3 = 4x

if you are looking for all real numbers your answer would be b & c.   if your looking for just numbers then your answer would be a & e. i hope this .
