(2x-3y=7)×5-----10x-15y=35____equation 1.
(5x+2y=10)×2-----10x+4y=20____equation 2.
equation 1-equation 2.
-19y=15
y= -15/19
put value of y in equation 1.
we get 38x=88
x=88/38 =44/19
(5x+2y=10)×2-----10x+4y=20____equation 2.
equation 1-equation 2.
-19y=15
y= -15/19
put value of y in equation 1.
we get 38x=88
x=88/38 =44/19
pikes:
2x-3(-15/19)=7
2x+45/19=7
38x+45=133
38x=133-45
x=88/38
x=44/19
why u have multiplied both 7 and 2x with 19
