Enter Equation or Inequality

Solve the following equation


Solve for x

2x + 1 = 3x - 3

Group variables

Group our variables 2x and 3x
subtract 3x from both sides

2x + 1 - 3x = 3x - 3 - 3x

Cancel 3x on the right side:

-x + 1 = -3

Group constants

Group our constants 1 and -3.
subtract 1 from both sides

-x + 1 - 1 = -3 - 1

Cancel 1 on the left side:

-x = -4

Divide each side of the equation by -1


x = 4

Final Answer

x = 4

What is the Answer?
x = 4
