Question

(3x+7) (2y-4) - (x+5) (3y-1)

Answer is 3xy-11x-y-23​

Answer 1

Answer: 3xy-11x-y-23​

Step-by-step explanation:

(3x+7)(2y−4)−(x+5)(3y−1)

Apply the distributive property by multiplying each term of 3x+7 by each term of 2y−4.

6xy−12x+14y−28−(x+5)(3y−1)

Apply the distributive property by multiplying each term of x+5 by each term of 3y−1.

6xy−12x+14y−28−(3xy−x+15y−5)

To find the opposite of 3xy−x+15y−5, find the opposite of each term.

6xy−12x+14y−28−3xy−(−x)−15y−(−5)

The opposite of −x is x.

6xy−12x+14y−28−3xy+x−15y−(−5)

The opposite of −5 is 5.

6xy−12x+14y−28−3xy+x−15y+5

Combine 6xy and −3xy to get 3xy.

3xy−12x+14y−28+x−15y+5

Combine −12x and x to get −11x.

3xy−11x+14y−28−15y+5

Combine 14y and −15y to get −y.

3xy−11x−y−28+5

Add −28 and 5 to get −23.

3xy−11x−y−23
