Question

If x+y =2/1, 1/2 ,2x-y=1/2,2/1 find value of x​

Answer 1

Answer:

X+Y= 2 ,2X-Y=2

multiple the eq by 2 we get

2X+2Y=4

by the method of elimination

2X+2Y=4

2X-Y=2

the solution is y= 2/3

put the value in any eq we get the value of X = 7/4

if the second eq is

2x-y=1/2

x+y= 2

then the value of x is 1/2
