Question

1) Write four solutions of the equations x + y = 8.​

Answer 1

Answer:

The four solutions are:

When x = 7, then y = 1  (7, 1)

When x = 6 then y = 2 (6,2)

When x = 5 then y = 3   (5, 3)

When x = 4  then y = 4  (4, 4)

Step-by-step explanation:

x + y = 8

Put y = 1

x + 1 = 8

x = 8 - 1

x = 7

Put y = 2

x + 2 = 8

x = 8 - 2

x = 6

Put y = 3

x + 3 = 8

x = 8 - 3

x = 5

Put y = 4

x + 4 = 8

x = 8 - 4

x = 4

Answer 2

Step-by-step explanation:

1. x =y-8
2. y =x-8
3. x+8= -y
4. y+8 = -x
