Question

solve by elimination method,3(2x+y)=7xy,3(x+3y)=11xy

Answer 1

2x+y = 7xy/3
x+3y = 11xy/3 ⇒ 2x+6y = 22xy/3

5y = 5xy
x = 1


2x+y = 7xy/3 ⇒ 6x + 3y = 7xy
x+3y = 11xy/3

5x = 10xy/3
1 = 2y/3
y = 3/2

Answer 2

6x+3y=7xy

3x+9y=11xy. =3x=11xy-9y

6x+3y=7xy

2(11xy-9y)+3y=7xy

22xy-18y+3y=7xy

15xy=15y

x=1

3x=11xy-9y

3×1=11×1×y-9y

3=11y-9y

y=3/2

I hope this will be helpful
