Martina is solving an equation. She shows her work below. 4x - 11 = 2x + 391 4x = 2x + 402 2x = 402 What did Martina do to the equation 4x = 2x + 402 to get 2x = 402?

added 11 on both sides in the line 2 and subtracted 2x from both sides in line 3 .@Brandon_Ray32

First off, Martina added 11 to both sides. For the second step, she subtracted 2x from both sides. The third step she would need to do is to divide 402 from 2x. Her answer would be x = 201. (:
