Subtract four times the quantity 2x +5 from three times the quantity 7x-8

13x-44

Step-by-step explanation:

three times the quantity we get 21x-24

four times the quantity we get 8x+20

then we collect like terms 21x-8x and -24-(+20)

21x-8x we get 13x

-24-(20) we get -44(use of direct numbers)

13 x - 44

Step-by-step explanation:

3 (7 x - 8) - 4 (2 x + 5)

21x-24-8x-20

21x-8x-24-20

13x-44
