clearing fractions and decimals, we have
125x + 5y = 21
3x + y = 3
now you can substitute y = 3-3x to get
125x + 5(3-3x) = 21
Now it's easy to solve for x, and then you can get y.
125x + 5y = 21
3x + y = 3
now you can substitute y = 3-3x to get
125x + 5(3-3x) = 21
Now it's easy to solve for x, and then you can get y.
