Diketahui:2x + y = 5x - 2y = 2Ditanya:5y + 5xJawab:x - 2y = 2x = 2y + 2Kemudian,2x + y = 52(2y + 2) + y = 54y + 4 + y= 55y = 5 - 45y = 1y = 1/5Lalu,2x + y = 52x + 1/5 = 52x = 5 - 1/52x = 25/5 - 1/52x = 24/5x = 24/5 ÷ 2x = 24/5 × 1/2x = 24/10x = 2,4Maka5y + 5x5(1/5) + 5(2,4)5/5 + 121 + 1213Simpulan:Nilai dari 5y + 5x dri persamaan 2x + y = 5 dengan x - 2y = 2 adalah 13
