Step-by-step explanation:

he...here your answer....

given equation ...

3x-4y-7=0. ......(1).

5x+2y-3=0. .......(2).

by use cross multiplication method .........

x/(b1c2-b2c1). = y/(c1a2-c2a1). = 1/(a1b2-a2b1).

so...

x/(12+14) = y/(-35+9). = 1/(6+20).

take here...

x/26= 1/26.

( x= 1)....

and ...

y/-26=1/26.

( y= -1)..

i hope this is right and helps u.
