Given y is 1.67x
Then
x + y = 0.56
x + 1.67x = 0.56
2.67x = 0.56
x = 0.56/2.67 = 0.209737827
Hence y = 0.350262172

x+y = 0.56
y is always 1.67 times higher than x, re-written that can be expressed as y = 1.67 x
Put this into your equation you have:
x+1.67X=0.56
2.67X = 0.56
0.56/2.65 = X
X = 0.211
Thats X done, now i hear you say what about Y? simple
Y = 1.67X again.
1.67 * 0.211 = Y
Y = 0.353

x + y = 0.56
then
x + 1.67x = 0.56
then
2.67x = 0.56
then
x = 0.209737827
y = 0.350262172

y = 1.57x
x +1.57x = 0.56
2.57x = 0.56
x = 0.56/2.57
x = 0.218
y = 0.342
