Question

Find the value of x and y if.(x+y,1)=(2,2x-y)​

Answer 1

Answer:

x is 1 and y is 1

Step-by-step explanation:

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

it means,

x + y = 2----> eq.1

2x - y = 1-----> eq.2

from eq.1

x = 2-y ----> eq.3

substitute in eq.2

2(2-y) - y = 1

4 - 2y - y = 1

4- 3y = 1

4 = 1+3y

3y = 3

y = 1

substitute y value in eq.3

x = 2-1

x = 1

Answer 2

Answer:

x=1;y=1

Step-by-step explanation:

x+y=2 ...(1)

2x-y=1 ...(2)

by elimination method

eq (1)*2 2x+2y=4

eq (2)*1 2x-y=1

now subtract 1 frrom 2

we get 3y = 3

             y=1

now substitute y=1 in (1)

we get 1+x=2

            x=1
