Question

Write four solutions of each of the following equations. 2 − 8 = 0​

Answer 1

Answer:

1)2x+y=9⟹y=9−2x

x=1 then y=9−2(1)=7

x=0 then y=9−2(0)=9

x=2 then y=9−2(2)=5

x=3 then y=9−2(3)=3

(0,9),(1,7),(2,5),(3,3) are four solutions

2)xy+y=9⟹y=

x+1

9

x=0 then y=

0+1

9

=9

x=1 then y=

1+1

9

=4.5

x=2 then y=

1+2

9

=3

x=8 then y=

1+8

9

=1

(0,9),(1,4.5),(2,3),(8,1) are four solutions

3)x=4y

y=0 then x=0

y=1 then x=4

y=2 then x=8

y=3 then x=12

(0,0),(4,1),(8,2),(12,3) are four solutions
