In the equation ( 81 = 3a - 8a - 4a ), the variable ( a ) represents an unknown quantity that we need to solve for. To simplify the right side, we combine the terms: ( 3a - 8a - 4a = -9a ). This gives us the equation ( 81 = -9a ). Solving for ( a ) involves dividing both sides by -9, resulting in ( a = -9 ).
