Question

solve cross multiplication question has 2 X + 3 Y equal to elevel and 2 x minus 4 Y equal to minus 24 ​

Answer 1

Step-by-step explanation:

2x+3y=11•••••••••••(i)

2x-4y=-24••••••••••(ii)

from eq.n (i)

2x=11-3y•••••••••••(iii)

& from eq.n (ii)

2x=-24+4y•••••••••(iv)

Now eq.n (iii)=(iv)

11-3y=-24+4y

=>-3y-4y=-24-11

=>-7y=-35

=>y=5

Now putting the value of y in eq.n (iii) we get

2x=11-3(5)

2x=11-15

2x=-4

x= -2

hence x=-2 & y= 5
