Solve the following equation

x+1+2x=4

Solve for x

x + 1 + 2x = 4

Group the x terms on the left:

(1 + 2)x = 3x

Form modified equation

3x + 1 = + 4

Group constants

Group our constants 1 and 4.
subtract 1 from both sides

3x + 1 - 1 = 4 - 1

Cancel 1 on the left side:

3x = 3

Divide each side of the equation by 3

3x
3
=
  
3
3

x = 1

Final Answer


x = 1
