Respuesta :

-3x + 50 = 101

       -50   -50      subtract 50 from both sides, 50's cancel out from the left.

___________     solve for 101 - 50.

-3x = 51

___  ___              divide -3 on both sides, -3's cancel out on the left.

-3     -3                 solve for 51 ÷ -3.

x = -17, is the answer.
