A+b+c=412
a-52=b/2=c/3
(a-52)+2c/3+c=412-52=360
c/3+2c/3+3c/3=360
6c/3=360
2c=360=>c=180
a=180/3+52=60+52=112
b=2X(180/3)=2X60=120

A + b + c = 412
a - 52= b : 2
a - 52 = c : 3
b = 2 * (a - 52)
c = 3 * (a - 52)
a + 2a - 104 + 3a - 156 = 412
6a = 412 + 104 + 156
6a = 672
a = 672 : 6
a = 112
b = 2 * (112 - 52)
b = 2 * 60
b = 120
c = 3 * (112 - 52)
c = 3 * 60
c = 180
