Question

Write four solution of each 2x +y=4

Answer 1

Answer:

the four solutions are (1,22),(0,4),(2,0),(3,-2)

Answer 2

Answer:

2x +y =4

put x =1. put x =2

2(1)+y=4. 2(2) + y =4

2 +y=4. 4 +y =4

y= 4-2. y=4-4

y=2.(1,2) y=0(2,0)

put x=-1. put x =0

2(-1) + y =4. 2(0) + y =4

-2 + y = 4. 0 + y = 4

y =4 +2. y = 4 (0,4)

y =6 (-1,6)
