Question

(7) 99x + 101y = 499; 101x + 99y = 501
pls answer me it's argent​

Answer 1

Answer:

x=3 y=2

Step-by-step explanation:

let 99x+101y=499 equation 1

and 101x+99y=501 equation 2

then, from equation 1

 $x= \frac{499-101y}{99}$, (transferring everything to Right-hand side, so I can evaluate x)

now put the value of this x in equation 2

$101X\frac{499-101y}{99}+99y=501$

Solve this, you will get y=2

now put the value of y in $x= \frac{499-101y}{99}$, you will get x=3

Answer 2
