First Degree Equation Solver

This calculator solves the first degree equations with one variable - the kind that is given in elementary school.

These equations are linear in nature and are characterized by having only one variable and one equation.

Usually, the solution is to simplify the equation to the form ax=b by expanding brackets and moving everything with "x" to the left hand side and everything without "x" to the right hand side of the equation.

Let's look at the example problem below.
To solve this equation, we will start by combining like terms on each side of the equation and then isolate x on left side. Here are the steps:

  1. Distribute the -2 on the left side: 3 - 10x - 8 = 13 - 4x.
  2. Add 4x to both sides: 3 - 6x -8 = 13
  3. Add 8 to both sides (or move -8 to the right, if you like): 3 - 6x = 21
  4. Subtract 3 from both sides (or move 3 to the right): - 6x = 18
  5. Divide both sides by -6: x = -3


In elementary school, it is easy to make mistakes, for example, in signs when expanding brackets and moving through an equal sign. Thus we create our First Degree Equation Solver to make the process of solving these equations simple and straightforward. It provides a convenient and reliable tool for checking solutions or for quickly finding the solution to an equation. The calculator shows the result of the simplification, which you also should get, and the answer, the value of x.
