Question

3x-4y=7 and 5x+2y-3=0 using cross multiplication method

Answer 1

Step-by-step explanation:

given equation ...

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

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

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

l

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

so...

so...

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

take here...

x/26= 1/26.

( x= 1)....

and ...

y/-26=1/26.

y/-26=1/26. ( y= -1)..

Answer 2

Answer:

x = -17/11 y=0

hope it may help u
