4x-5y=2 dan 3x-5y=-1​

A. The local police asked the F.B.I. to assist with the case. -F.B.I isn't properly punctuated, as there's a period after 'F.B.I', which implies the sentence ends there.
B. Mary remembered to buy milk didn't she? -Should be 'Mary remember to buy milk, didn't she?'
C. Mr. Jones visited the YMCA before becoming a member. -This is correct
D. The company held it's annual party at the convention center. -It's isnt proper, It's is basically 'it is', The company held it is annual party at the convention center obviously does not make sense.

Penjelasan dengan langkah-langkah:Eliminasi dari 2 persamaan diatas, karena nilai y sama yaitu -5y, maka tinggal dilakukan pengurangan seperti berikut4x-5y=23x-5y=-1_______-x = 3Ditemukan nilai x yaitu 3, maka untuk mencari nilai y, masukkan nilai x pada salah satu persamaan4x-5y=2 -> 4(3)-5y=2 -> 12-5y=2 -> 5y=10 -> y=2Maka didapatkan nilai x=3 dan y=2
