Linear Equation Solver

Solve a first-degree equation in one variable and inspect the exact isolation steps used by the certified calculation engine.

Solution x4
Equation residual
0
Methodology

The certified algebra engine isolates x from ax + b = 0; the displayed steps and result use the same validated inputs.

Solution steps
  1. 2x + -8 = 0
  2. 2x = 8
  3. x = 4

How this calculator works

For ax + b = 0 with non-zero a, subtract b from both sides and divide by a, giving x = -b / a.

Formula

For ax + b = 0, x = -b / a

Isolate x by subtracting b and dividing by the non-zero coefficient a.

Worked example

2x - 8 = 0 is a verified test case used by the calculation engine.

Assumptions and limitations

  • Coefficient a must be non-zero.
  • Inputs are finite real numbers.
