Answer:
x=9/13 and y=-5/13
Step-by-step explanation:
3x-5y=4 .......1
9x-2y=7 .......2
substituting eq 1ad 2
by using multipication method , we get
eq1*2 6x -10y=8
eq2*5 45x-10y=35
___________
-39x=-27
____________
x=27/39
x=9/13
substituting value of x in eq1
⇒ 3x-5y=4
⇒3(9/13) -5y=4
⇒27/13-5y=4
⇒27-65y/13=4
⇒27-65y=52
⇒-65y=25/65
⇒y=-5/13
therefore , x=9/13 and y=-5/13
