Answer 2

To simplify the given expressions, let's rewrite them using parentheses to indicate the order of operations:

Expression 1: (5x - 3/2) / (3 - 5x/7) Expression 2: (9y - 2/5) / (2 - 9y/3)

Please note that I've assumed the variables in the expressions are x and y, respectively.

Now, let's simplify each expression one by one:

Expression 1: (5x - 3/2) / (3 - 5x/7) To simplify, let's find a common denominator for the fractions: Expression 1: (10x - 3) / (6 - 5x/7) To divide by a fraction, we can multiply by its reciprocal: Expression 1: (10x - 3) * (7/5x - 6) Expanding the expression: Expression 1: (70x - 21) / (30x - 36)

Expression 2: (9y - 2/5) / (2 - 9y/3) Similarly, let's find a common denominator for the fractions: Expression 2: (45y - 2) / (10 - 3y/3) Simplifying further: Expression 2: (45y - 2) / (10 - y)
