Question

in two numbers 2 times of the second number is subtracted from 5 times of the first number gives 40. three times of the second number is subtracted from four times of the first number gives 25. what are the numbers?​

Answer 1

math na to ase mare ha na kisna mare hogi

Answer 2

Step-by-step explanation:

numbers be x and y.

2y-5x=40(1 equation )

3y-4x=25(2nd equation )

we cannot add or substract, because any numbers(x&y) no cancelled.

1 equation multiplied by 3

and 2nd equation multiplied by 2

Then,

6y-15x=120(3rd equation )

6y-8x=50(4th equation )

_____________________

0-7x=70

x=70/2

=10

x=10//

Then, y=

2y-5x=40

2y-5×10=50=40

2y=40±50

2y=90

y=90/2=45

y=45//
