tolong jawab kak

<p>Dari kesamaan matriks itu diperoleh data&nbsp;</p><p>2x - 5y = 1 &nbsp;dan 3x + 4y = 13 &nbsp; &nbsp; &nbsp; ini dapet dari kalihin x dan y sama yg ada di kolom matriks &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;sebelah kiri terus di = sama kolom yg paling kanan&nbsp;</p><p>terus &nbsp;eliminasi x dulu&nbsp;</p><p>klo eliminasi x brarti x nya harus sama dulu ya , yg &nbsp;2x - 5y = 1 &nbsp;dikali 3 semua &nbsp;terus yg &nbsp;3x + 4y = 13 &nbsp;dikali 2 &nbsp;semua</p><p>&nbsp;jadi&nbsp;</p><p>6x - 15y = 3&nbsp;</p><p>6x + 8y = 26 terus dikurangi&nbsp;</p><p>x nya habis &nbsp;jadi tinggal</p><p>-15y - 8y = 3-26</p><p>-23y= -23</p><p><strong>y = 1&nbsp;</strong></p><p>nah substitusiin y nya ke persamaan 2 atau 1 terserah tapi aku mau pake persamaan 2&nbsp;</p><p>&nbsp;3x + 4y = 13 &nbsp; &nbsp;</p><p>&nbsp;3x + 4 . 1 = 13</p><p>3x = 9</p><p><strong>x = 3&nbsp;</strong></p><p>&nbsp;<strong>nah jadi deh y = 1 dan x = 3</strong></p><p>&nbsp;</p><p><strong>SELESAI YEYY !!!!!</strong></p><p>&nbsp;</p><p>&nbsp;</p><p>&nbsp;</p>
