Linear Equation Calculator
Solve ax + b = c
System of 2 Equations
a₁x + b₁y = c₁ and a₂x + b₂y = c₂
Formula
ax + b = c → x = (c-b)/a | Cramer's rule for systems
Frequently Asked Questions
How do I solve a system of two linear equations?
Use Cramer's rule: for a₁x+b₁y=c₁ and a₂x+b₂y=c₂, find determinant D=a₁b₂-a₂b₁. Then x=(c₁b₂-c₂b₁)/D and y=(a₁c₂-a₂c₁)/D. If D=0, there's no unique solution.
