Best Answer

ab = 108 => a != 0, b != 0

so we CAN write b = 108 / a

a + 108 / a = 56

Multiply both side by a

a^2 + 108 = 56a. It's a simple quadratic equation, it will always have a solution over the Complex number, may be even REAL roots.

so when you are done with a, move on to b.

This is hardly abstract.
