Question

7b-3y:8b-6y-(3b+5y):(7b+5y) упростить выражения

Answer 1

-3у-6у:7b+8b-(-3b)-5у:7b+5y

Answer 2

To simplify the expression, let's first combine like terms and then perform the indicated operations. The given expression is:

7b - 3y + 8b - 6y - (3b + 5y) / (7b + 5y)

Step 1: Combine like terms Combine the terms with 'b' and the terms with 'y':

(7b + 8b - 3b) + (-3y - 6y - 5y) / (7b + 5y)

Simplify:

12b - 14y / (7b + 5y)

Step 2: Factor out the common terms in the denominator Factor out 'b' from the first term and 'y' from the second term in the denominator:

12b - 14y / b(7 + 5y)

Step 3: Simplify further Now, we can cancel out common terms in the numerator and denominator:

(2(6b - 7y)) / (b(7 + 5y))

The final simplified expression is:

(12b - 14y) / (b(7 + 5y))

This is the simplified form of the given expression.
