The Best Linear Equation Solver Online

Our linear equation solver handles any one-variable equation instantly. Whether it's a simple ax + b = c equation or a complex equation with variables on both sides, we show you exactly how to solve it step-by-step. Perfect for algebra homework, test prep, and understanding the solving process. No signup, no adsโ€”just instant accurate results.

Standard Form

ax + b = c โ†’ x = (c - b) / a

Isolate x by subtracting b, then dividing by a

Both Sides

ax + b = cx + d โ†’ x = (d - b) / (a - c)

Move all x terms to one side, constants to other

System (Substitution)

Solve one equation for x, substitute into the other

Works for any 2ร—2 system

Examples

2x + 3 = 11

12x = 11 - 3
22x = 8
3x = 8 รท 2 = 4

3x - 7 = 2x + 5

13x - 2x = 5 + 7
2x = 12

(x + 2)/3 = 5

1x + 2 = 5 ร— 3
2x + 2 = 15
3x = 13

Frequently Asked Questions

What is a linear equation?

A linear equation is an equation where the highest power of the variable is 1 (like x, not xยฒ). Examples: 2x + 3 = 7, x/4 - 5 = 10.

How do I solve a linear equation?

Isolate the variable by performing inverse operations: first add/subtract constants, then multiply/divide by the coefficient.

Is this solver free?

Yes! 100% free with no signup required. Solve unlimited equations.

Can it solve equations with fractions?

Yes! Just enter your equation and we'll show you step-by-step how to clear the fractions and solve.
