Answer 1

ɢɪᴠᴇɴ ᴇǫᴜᴀᴛɪᴏɴ ɪs:

2x+ʏ=7

ғᴏʀ x = - 1, ᴡᴇ ɢᴇᴛ

−2+ʏ=7

⇒ʏ=9

∴ (-1, 9) ɪs ᴀ sᴏʟᴜᴛɪᴏɴ.

ғᴏʀ x = 0, ᴡᴇ ɢᴇᴛ

⇒0+ʏ=7

⇒ʏ=7

∴ (0, 7) ɪs ᴀ sᴏʟᴜᴛɪᴏɴ.

ғᴏʀ x = 1, ᴡᴇ ɢᴇᴛ

⇒2+ʏ=7

⇒ʏ=5

∴ (1, 5) ɪs ᴀ sᴏʟᴜᴛɪᴏɴ.

ғᴏʀ x = 2, ᴡᴇ ɢᴇᴛ

⇒4+ʏ=7

⇒ʏ=3

∴ (2, 3) ɪs ᴀ sᴏʟᴜᴛɪᴏɴ.

ʜᴇɴᴄᴇ, ᴡᴇ ʜᴀᴠᴇ ғᴏᴜʀ sᴏʟᴜᴛɪᴏɴ (−1,9),(0,7),(1,5)ᴀɴᴅ(2,3)
