Answer :

Answer:

x+y=4

x=2 and y=2

2+2=4

2x-y=5

2×2-2=5

4-2=5

2=5

Answer:

x + y =4 (eq no.1)

2x – y=5(eq no.2)

x + y =4

=> x = 4 –y

now put the value of x in eq no.2

2×(4–y)–y =5

=> 8–2y =5

=> –2y–y =5–8

=> –3y = –3

=> cancel (–) from both sides

=> 3y = 3

=> y = 3/3

=> y = 1

Now put VALUE of y in eq no.1

=> x + 1 =4

=> x = 4–1

=> x =3

Now Put both Values of x and y and you found your answer correct

3 + 1 =4

4=4
