Answer:
705
Step-by-step explanation:
Set up are variables:
x a page number
x + 1 the page after x
Now can set up our equation
x + x + 1 = 1411
Now we combine like terms:
2x + 1 = 1411
2x = 1410
x = 705
x + 1 = 706
Check our work:
705 + 706 = 1411 works so we have the right numbers
706 would be the page join is on and 705 would be the page job is on
