Answer:x+y=10. ...(1)x-y=12. ...(2) Add (1) and (2)-(x+y)+(x-y)=10+122x=22
Answer:x+y=10. ...(1)x-y=12. ...(2) Add (1) and (2)-(x+y)+(x-y)=10+122x=22x=11
Answer:x+y=10. ...(1)x-y=12. ...(2) Add (1) and (2)-(x+y)+(x-y)=10+122x=22x=11Now put value of x in (1)
Answer:x+y=10. ...(1)x-y=12. ...(2) Add (1) and (2)-(x+y)+(x-y)=10+122x=22x=11Now put value of x in (1)x+y=10
Answer:x+y=10. ...(1)x-y=12. ...(2) Add (1) and (2)-(x+y)+(x-y)=10+122x=22x=11Now put value of x in (1)x+y=1011+y=10
Answer:x+y=10. ...(1)x-y=12. ...(2) Add (1) and (2)-(x+y)+(x-y)=10+122x=22x=11Now put value of x in (1)x+y=1011+y=10y=(-1)
Answer:x+y=10. ...(1)x-y=12. ...(2) Add (1) and (2)-(x+y)+(x-y)=10+122x=22x=11Now put value of x in (1)x+y=1011+y=10y=(-1) Hence anwer is (B)
