Question

write 2 different linear equations in two variables and find four solutions for each of them​

Answer 1

1. 2x+y=7

2. x=4y

1. 2×0+y=7

0+y=7

y=7

Let y =0

2x+y=7

2x+0=7

2x =7

x=7/2

Let x=1

2x+y=7

2×1+y=7

2+y=7

y=7-2

y=5

Let x=2

2x+y=7

2×2 +y=7

4+y=7

y=7-4

y=3

(0,7),(7/2,0),(1,5),(2,3).

2. x=4y

Let x=0

x=4y

0=4y

y=0/4=0

Let x=1

x=4y

1=4y

y=1/4

Let y=1

x=4y

x=4×1

x=4

Let x=2

x=4y

2=4y

y=2/4

y=1/2

(0,0),(1,1/4),(4,1),(2,1/2).
