Question

Check which of the following are solutions of the equation x-2y=4 *​

Answer 1

Answer:

Step-by-step explanation:

(-2,-3)(-1,-5/2)(0,-2)(1,-3/2)(2,-1)(3,-1/2)(4,0)(6,1)(8,2)(10,3)

Answer 2

Step-by-step explanation:

x-2 y=4  equations 1

or,x+4=2y

or,x= 2y/4

or,x= y/2    equations 2

by putting value of x in equations 1

or,x-2y=4

or,y/2-4=2y

or,y-8=4y

or,-8/3=y

and by taking equqtions 1

or,x-2y=4

or,x-2*(-8/3)=4

or,x+(16/3)=4

or,16x/3=4

or,=12/16

x=3/4

hence the value of x is 3/4 and y is -8/3
