Cross multiplication method 5/2x + 2/3y = 7 & 3/x +2/y=12​

Answer»

Answer:

5/2X+ 2/3y =7

15y/6xy +6x/6xy =7(make the denominator same)

15y+6x/6xy =7

by cross multiplication,

15y+6x = 42 XY

solve the remaining....

3/x + 2/y =12

3y/xy +2x/xy =12 (make the denominator same)

3y+2x/ xy =12

by cross multiplication

3x+ 2x =12xy

solve the remaining
