Subtract. -(3a+3x)/(2a)-(8a-9x)/(2a) Simplify your answer as much as possible. square

To subtract the given fractions, we need to have a common denominator. In this case, the common denominator is $2a$. <br /><br />First, let's rewrite the fractions with the common denominator:<br /><br />$-\frac {3a+3x}{2a}-\frac {8a-9x}{2a}$<br /><br />Now, we can combine the numerators:<br /><br />$-\frac {(3a+3x)+(8a-9x)}{2a}$<br /><br />Simplifying the numerator:<br /><br />$-\frac {11a-6x}{2a}$<br /><br />Therefore, the simplified answer is:<br /><br />$\boxed{-\frac {11a-6x}{2a}}$
