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.
