Harrison Bullock · Answer 1

The old machine can produce 100 copies/hour

Step-by-step explanation:

x = number the old machine can produce per hour

2x+5=205

2x=200

x=100

Baylee Allison · Answer 2

100

Step-by-step explanation:

take the words 5 more or plus 5+, than twice (2) a number or the amount the old machine can use (x). put it together to get 5+2x now the new one can produce 205 copies total. we use total as equal so, 5+2x=205, subtract 5 on both sides. 2x=200 and divide by 2 to both sides. x=100
