x+y+z=\frac{1}{10}\times 3
Multiply both sides by 3.
x+y+z=\frac{3}{10}
Multiply \frac{1}{10} and 3 to get \frac{3}{10}.
x+z=\frac{3}{10}-y
Subtract y from both sides.
x=\frac{3}{10}-y-z
Subtract z from both sides.
x+y+z=\frac{1}{10}\times 3
Multiply both sides by 3.
x+y+z=\frac{3}{10}
Multiply \frac{1}{10} and 3 to get \frac{3}{10}.
y+z=\frac{3}{10}-x
Subtract x from both sides.
y=\frac{3}{10}-x-z
Subtract z from both sides.
