Solve the following equation

11+x-2=3x-11

Solve for x

11 + x - 2 = 3x - 11

Group the constants on the left

11 - 2 = 9

Form modified equation

x + 9 = 3x - 11

Group variables

Group our variables x and 3x
subtract 3x from both sides

x + 9 - 3x = 3x - 11 - 3x

Cancel 3x on the right side:

-2x + 9 = -11

Group constants

Group our constants 9 and -11.
subtract 9 from both sides

-2x + 9 - 9 = -11 - 9

Cancel 9 on the left side:

-2x = -20

Divide each side of the equation by -2

-2x
-2
=
  
-20
-2

x = 10
