4x + 3y =12
4x = 12.- 3y
x = 12.- 3 y / 4
put the value in second equ....
5x - 2y = 15.
5 （12.- 3y / 4 ） - 2y = 15
（ 60 -15.y / 4 ） - 2y = 15
LCM Lene par
60 - 15 y - 8y = 60
60 - 23 y =60
4x = 12.- 3y
x = 12.- 3 y / 4
put the value in second equ....
5x - 2y = 15.
5 （12.- 3y / 4 ） - 2y = 15
（ 60 -15.y / 4 ） - 2y = 15
LCM Lene par
60 - 15 y - 8y = 60
60 - 23 y =60
