Question

(2x+y,2)=(1,x-y). with full process​

Answer 1

Step-by-step explanation:

Here,

(2x + y , 2) = ( 1, x - y )

Then,

2x + y = 1 ..........1st equation

x - y = 2

x = 2 + y ...............2nd equation

Now , by substitution method

Taking 1st equation,

2x + y = 1

2( 2 + y ) + y = 1

4 + 2y + y = 1

4 + 3y = 1

y = -3/3

y= -1

Now,

Taking 2nd equation,

x = 2 + y

x= 2 + ( -1)

x= 1

Hence,

y= -1

x= 1
