Question

Find the four solutions. 2x-y=4​

Answer 1

Answer:

Step-by-step explanation:

2x-y=4

(i) put x=0

then,

2(0)-y=4

y=-4    

(ii) put x=1

then,

2(1)-y=4

y=-2

(iii) put x=2

then,

2(2)-y=4

y=0

(iv) put x=3

then,

2(3)-y=4

y=2

Hence the four solutions are,

x=0,y=-4

x=1,y=-2

x=2,y=0

x=3,y=2
