Solving First Degree Equations with Two Unknowns
Online calculator and solving procedure for two equations with two unknowns. Solve systems of first degree equations in the form: a1*x + b1*y = c1 and a2*x + b2*y = c2
Solving First Degree Equations with Two Unknowns
First degree equations with two unknowns can be expressed as:
Equation 1: a₁x + b₁y = c₁
Equation 2: a₂x + b₂y = c₂
Solution Method
This calculator solves the system using the elimination/substitution method:
- Rearrange equation 1 to express y in terms of x
- Substitute into equation 2 to solve for x
- Back-substitute to find y
Example
For the equations:
- 3x + 5y = 7
- 4x - 3y = 19
The solution is: x = 4, y = -1
