​

Answer 1

Answer:

Find three different solution of the equation

10x + 11y = 21

ANSWER

Given equation 10x+11y=21

(i)10x+11y=21

If y=1 put in equation we get

10x+11×1=25

⇒10x+11=21

⇒10x=21−11=10

⇒x=1

(1,1)

(ii)10x+11y=21

If y=2 put in equation we get

10x+11×2=21

⇒10x+22=21

⇒10x=21−22=−1

⇒x= 10

(iii)10x+11y=21

If y=3 put in equation we get

10x+11×3=21

⇒10x+33=21

⇒10x=21−33=−12

⇒x=
