Linear Equation Solver
Solve a linear equation in the form ax + b = c and see the isolation steps.
Inputs and results stay in this browser. Change one value at a time to explore the relationship.
Calculation steps
- Start with 3x + 6 = 18.
- Subtract 6 from both sides: 3x = 12.
- Divide by 3: x = 4.
Definition and formula
Subtract the constant term from both sides, then divide both sides by the coefficient of x.
x = (c − b) ÷ a
Worked example
For 3x + 6 = 18, subtract 6 to get 3x = 12, then divide by 3: x = 4.
Common mistake
Whatever operation is applied to one side of an equation must also be applied to the other side.
How to learn with this calculator
Begin with the worked example, then change one value while keeping the others fixed. Compare the new result and calculation steps to identify which part of the formula changed.
