Answer: x + y = 392 , x - y = -12
Step-by-step explanation:
Let x be the number of page 1 and y be the number of page 2 in the textbook,
Since, the total number of pages = 392
⇒ x + y = 392
Also, paper 1 is 12 pages less than paper 2.
⇒ x = y - 12
⇒ x - y = - 12
Thus, the given pair of equations that shows the given situation is,
x + y = 392 , x - y = -12
