Solve linear equations and systems of equations with our free online linear equation calculator. Get step-by-step solutions and detailed explanations for better understanding.
Enter an equation above to see the step-by-step solution.
ax + b = 0, where a and b are constants and x is the variable.
y = mx + b, where m is the slope and b is the y-intercept.
y - y₁ = m(x - x₁), where (x₁, y₁) is a point on the line.
Linear equations graph as straight lines in the coordinate plane.
2x + 3 = 7 → x = 2
2x + 3y = 7, x - y = 1 → x = 2, y = 1
A linear equation is an equation where the highest power of the variable is 1. It forms a straight line when graphed and has the general form ax + b = 0.
To solve a linear equation, isolate the variable by performing the same operations on both sides. Add/subtract terms to get variables on one side, then divide by the coefficient.
For systems of linear equations, you can use substitution, elimination, or matrix methods. The calculator can handle both single equations and systems.
