Two-sided linear equation solver
Enter an equation with x on both sides and see how variable terms are collected before x is isolated.
Try an example
Equations such as 5x - 3 = 2x + 12 are still linear. Solving starts by moving variable terms to one side and constants to the other while keeping the equation balanced.
When the x terms cancel completely, the remaining statement determines whether there is no solution or infinitely many solutions.
The solver subtracts or adds the variable term from one side, then moves the remaining constant and divides by the final x coefficient when necessary.
For identities and contradictions, the calculator stops at the logical result instead of attempting an invalid division by zero.
Type or paste an equation, solve it, inspect the transformations, and use verification and the graph instead of relying on the final value alone.
5x - 3 = 2x + 127x + 4 = 3x + 202(x + 3) = x + 102x + 5 = 2x + 9Follow the same steps the calculator uses for three equations in this category.
x = 5
Subtract 2x from both sides
5x-3=2x+12 → 3x-3=12
Add 3 to both sides
3x-3=12 → 3x=15
Divide both sides by 3
3x=15 → x=5
Verified
x = 4
Subtract 3x from both sides
7x+4=3x+20 → 4x+4=20
Subtract 4 from both sides
4x+4=20 → 4x=16
Divide both sides by 4
4x=16 → x=4
Verified
x = 4
Subtract x from both sides
2x+6=x+10 → x+6=10
Subtract 6 from both sides
x+6=10 → x=4
Verified
Substitute each answer into the original equation and compare both sides.
Cubic and higher-degree polynomials, logarithmic, exponential, trigonometric, nested-radical, and multiple-absolute-value equations remain outside the supported solver scope.
