Solution 1

To solve this problem, we need to use the concept of ratios and proportions.

Step 1: From the first equation, we can write a = 3(b+c)

Step 2: From the second equation, we can write c = 7/5(a+b)

Step 3: Substitute a from equation 1 into equation 2, we get c = 7/5(3(b+c)+b) = 21/5(b+c) + 7/5b
