Question

A company has two manufacturing plants with daily production levels of 9 x plus 149x+14 items and 7 x minus 57x−5 ​items, respectively. The first plant produces how many more items daily than the second​ plant?

Answer 1

first plant: 9x + 14x +14
second plant: 7x - 5x -5

first plant: 23x + 14
second plant: 2x - 5

=(23x + 14) - (2x - 5)
=23x + 14 - 2x + 5

=21x + 14 - 2x + 5

=21x + 19

the first plant produces 21x + 19 more items daily than the second plant
