let 2 X + 3 Y - 6 equal to zero
and 3 X + 7 y plus one equal to zero
multiply 3 to first equation
multiply 2 with second equation
substrate equation 1 from equation 2
6 X + 9 Y - 18 - 6x- 7y -2 equal to zero
2 y - 20 equals to 0
2y = 20 Y equal to 10
2 X + 3 Y equal to 6
2 X + 30 equal to 6
2x equals to -24
x =-12
and 3 X + 7 y plus one equal to zero
multiply 3 to first equation
multiply 2 with second equation
substrate equation 1 from equation 2
6 X + 9 Y - 18 - 6x- 7y -2 equal to zero
2 y - 20 equals to 0
2y = 20 Y equal to 10
2 X + 3 Y equal to 6
2 X + 30 equal to 6
2x equals to -24
