Question

Find four solutions of the linear equation 2x – y = 4.

Answer 1

Step-by-step explanation:

i) put x=0 then,

2(0)-y=4y=-4

ii) put x=1 then,

2(1)-y=4y=-2

iii) put x=2then,

2(2)-y=4y=0

iv) put x=3 then,

2(3)-y=4y=2

Therefore the 4 solutions are

x=0. y=-4

x=1. y=-2

x=2. y=0

x=3. y=2

Answer 2

Answer:

$2 \times 2 - 0 = 4$

$2 \times 0 - ( - 4) = 4$

$2 \times 1 - ( - 2) = 4$

$2 \times 3 - 2 = 4$

Therefore the 4 solutions are: (2,0),(0,-4),(1,-2),(3,2).

Answer may vary from taking the value different for x and y. One should remember that the values for x and y can be changed but the value for the answer remains unchanged.
