Question

find any three solution of 2x+y=7 ?​

Answer 1

Answer:

given that 2x+y=7

then y=7-2x

let the values of x to find y

if x=0 then y =

y= 7-2(0)

y=7 ans;1

if x=1 then y=

y=7-2(1)

y=7-2=5

y=5. ans;2

if x= 2 then y=

y=7-2(2)

y=7-4

y=3. ans;3

Answer 2

Answer:

2x=7-y

Step-by-step explanation:

1 solution

put x=0

2x+y=7

2(0)+y=7

0+y=7

y=7

2 solutions

put y=2

2x+y=7

2(2)+y=7

4+y=7

y=7-4

y=3

3 solution

put x=3

2x+y=7

2(3)+y=7

6+y=7

y=7-6

y=1
