Question

Solve by rule of cross multiplication method: 7x – 15y – 2 = 0 and x + 2y – 3 = 0.​

Answer 1

Answer:

7x-15y-2=0 ---------(I)

x+2y-3=0 -----------(II)

x/(-15)×(-3)-2×(-2)=y/-2-3×7=1/7×2-(-15)

or, x/45+4=y/-2-21=1/14+15

or, x/49=y/-23=1/29

So, x/49=1/29

or, x=49/29

y/-23=1/29

or, y=-23/29
