    Answer:

    328 pages for the novel

    123 pages for the second day

    Step-by-step explanation:

    Let the number of pages of the novel = x

    Raw Equation

    (1/4)x + 1/2 (3/4)x + 123 = x

    Solution

    (1/4)x + (3/8)x+ 123 = x

    Change the fractions to common denominators.

    (2/8)x + (3/8)x + 123 = x

    Add the fractions.

    (2/8 + 3/8)x + 123 = x

    Subtract (5/8)x from both sides.

    (5/8)x + 123 = x

    (5/8)x- (5/8)x + 123 = x – (5/8)x

    Multiply both sides by 8

    123 = (3/8)x  

    123 * 8 = 3x

    Divide by 3

    984 = 3x

    984/3 = 3x / 3

    328 = x

    ===================

    At the end of the second day, she read 3/8 * 328 = 123 pages.
