x+y+z = 4202
y = 3x
z = 3x + 2
3x+3x+x + 2 = 4202
7x = 4202- 2
x = 4200 / 7
x= 600
y = 3 x 600 = 1800
z = 1800+ 2 = 1802
1800+1802+600 = 4202
y = 3x
z = 3x + 2
3x+3x+x + 2 = 4202
7x = 4202- 2
x = 4200 / 7
x= 600
y = 3 x 600 = 1800
z = 1800+ 2 = 1802
1800+1802+600 = 4202
x+y+z=4202
y=3
z=3*+2
3*+3*+2+2=4202
7*=4202-2
x=4200\7
x=600
y=3*600=1800
z=1800+2=1802
1800+1802+600=4204
