Diketahui tiga buah bilangan. Bilangan pertama ditambah bilangan kedua sama dengan dua kali bilangan ketiga. Selisih bilangan pertama dan ketiga sama dengan empat kali bilangan kedua. Jika jumlah ketiga bilangan sama dengan 15, nyatakan ke dalam model matematika!

x+y=2zx+y=2z
x+z=4yx+z=4y
x+y+z=15x+y+z=15

x+y=2zx+y=2z
xz=4yx-z=4y
x+y+2z=15x+y+2z=15

x+y=2zx+y=2z
xz=4yx-z=4y
x+y+z=15x+y+z=15

x+y=zx+y=z
xz=4yx-z=4y
x+y+z=15x+y+z=15

x+y=2zx+y=2z
xz=2yx-z=2y
x+y+z=15x+y+z=15
