Answer:

(a+b)+c = 71/28

Step-by-step explanation:

To solve this equation, we first need to simplify the expression on the right side of the equation:

(5/4 + 3/2) - 6/7

To add fractions, we need to find a common denominator. In this case, the common denominator is 4*2*7 = 56.

(5/4 + 3/2) - 6/7

= (35/28 + 84/28) - 48/28

= (119/28) - 48/28

= 71/28

Now, we can substitute this value back into the original equation:

(a+b)+c = 71/28

Therefore, the solution to the equation is:

(a+b)+c = 71/28
