Question

(ii) 99x + 101y = 499xy 101x + 997 = 501xy. by substitution method
very urgent plss help​

Answer 1

Step-by-step explanation:

99x+101y= 499 eq1

101x+99y=501. eq2

add equ1 and 2

200x+200y=1000

so divide with 200

x+y=5. eq3

same way sub eq1 and 2

-2x+2y =-2

divide with -2

x-y=1. eq4

now solve eq3 and 4 by substitution method

from eq4

x=1+y

put that in 3

1+y+y=5

2y=4

y=2

put y values in eq4

x-2=1

x=3
