Answer:
2x+y=35 (equation 1)
3×+4y=65 (equation 2)
Let the first equation;-
2x+y=35
2x=35-y
x=(35-y)/2 (equation 3)
Putting this value into equation 2
3x+4y=65
3[(35-y)/2]+4y=65
(105-3y)/2 + 4y=65
(105-3y+8y)/2=65
105+5y=130
5y=130-105
5y=25
y=5
x=(35-y)/2
x=(35-5)/2
x=30/2
x=15
I hope it is useful for you.
Thanks
