Question

the solution of equation x-2y=4 is​

Answer 1

Answer:

Step-by-step explanation:

Use hit and trial method.

Example,

when x = 0, y = -2

when y = 0, x = 4 and so on....

now let us rearrange the equation

x-2y=4

x=4+2y

now let us assume

y=0

x=4+2(0)

x=4

one solution is (4,0)

let y= -2

x=4+2(-2)

x=4-4

x=0

another solution is (0,-2)
