Dengan caranya

<p>Misalkan,</p><p>x &nbsp; &nbsp; &nbsp;= Bayaran Kevin Per Jam Dalam Dolar&nbsp;</p><p>x+3 = Bayaran Jesse Perjam Dalam Dolar &nbsp;</p><p>^ → persamaan (1)</p><p>&nbsp;</p><p>1. Setelah 8 jam bekerja, maka Jumlah bayaran mereka masing- &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;masing.&nbsp;</p><p>&nbsp; &nbsp; &nbsp;Kevin = 8x. &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;</p><p>&nbsp; &nbsp; &nbsp;Jesse = 8(x+3). &nbsp;</p><p>&nbsp;2. Jumlah Bayaran mereka masing setelah Jesse memberikan &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;10% bayaranya ke Kevin. &nbsp;</p><p>&nbsp; &nbsp; &nbsp; Kevin &nbsp;= 8x + 10% dari 8(x+3) = 8x + (8(x+3))/10. &nbsp;</p><p>&nbsp; &nbsp; &nbsp; Jesse = &nbsp;8(x+3) - 10% dari 8(x+3) = 8(x+3) - (8(x+3))/10.</p><p>&nbsp;3. Setelah itu, &nbsp;jumlah bayaran mereka menjadi sama.</p><p>&nbsp; &nbsp; &nbsp; Kevin = Jesse.</p><p>&nbsp; &nbsp; &nbsp; 8x + (8(x+3))/10 = 8(x+3) - (8(x+3))/10.</p><p>&nbsp;</p><p>&nbsp; &nbsp; &nbsp; &nbsp;Setelah persamaan sudah didapat, cari nilai x &nbsp;kemudian &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;subsitusikan ke persamaan (1).&nbsp;</p><p>&nbsp;</p><p>&nbsp; &nbsp; &nbsp; &nbsp;(80x + 8(x+3))/10 = (8(10x+30) - 8(x+3))/10 &nbsp;</p><p>&nbsp; &nbsp; &nbsp; &nbsp; 80x + 8(x+3) = 8(10x+30) - 8(x+3)</p><p>&nbsp; &nbsp; &nbsp; &nbsp; 80x + 8x + 24 = 80x + 240 - 8x - 24</p><p>&nbsp; &nbsp; &nbsp; &nbsp;88x + 24 = 72x + 216</p><p>&nbsp; &nbsp; &nbsp; &nbsp;88x = 72x + 192 &nbsp;</p><p>&nbsp; &nbsp; &nbsp; 16x = 192. &nbsp;→ Artinya, &nbsp;x = 12.</p><p>&nbsp;</p><p>4. Subtitusi.</p><p>&nbsp; &nbsp; Bayaran Kevin Per Jam Dalam Dolar = x = 12</p><p>&nbsp; &nbsp; Bayaran Jesse Per Jam Dalam Dolar = x + 3 = 12 + 3 = 12.</p><p>&nbsp;</p><p>Silakan mau pake gambar atau pake teks diatas.
