Solving First Degree Equations with Two Unknowns
Online calculator and solbing procedure for two equations with two unknowns.
First degree equations with two unknowns can be expressed as
a_{1} x + b_{1} y = c_{1} (1)
a_{2}x + b_{2}y = c_{2}(2)
Example  Two Equations with Two Unknowns
The two equations
3 x + 5 y = 7
4 x  3 y = 19 <
with the two unknown x and y can be solved by rearranging (1) to
y = (7  3 x) / 5
and substituting this expression for y in (2)
4 x  3 ((7  3 x) / 5 ) = 19
 the value for x can then be calculated to
x = 4
By substituting this value for x in expression 1
3 4 + 5 y = 7
 the value for y can be calculated to
y = 1
