The quickest and easiest way is to use equations 2 and 3 and find expressions for A and C in terms of B and then substitute those into equation 1.
You then solve for B and go back and solve for A and C.
2.

Now go back to equation 1.
1.
Let's multiply both sides by (4*5) to get rid of the denominators.
From our derivation above for A,
From equation 1,
