Step-by-step explanation:
-9x+7y=-15
-8x+y=18
------------------
y=18-(-8x)=18+8x=8x+18
----------------------------------
-9x+7(8x+18)=-15
-9x+56x+126=-15
47x+126=-15
47x=-15-126
47x=-141
x=-141/47
x=-3

24+y=18
y=18-24=-6
x=-3, y=-6.

Step-by-step explanation: If she has 140 pages left to read, and completed 2/5 of the book last week, and 1/4 of the book this week, then we have to divide the pages left to read (140) by the fraction of pages she read last week (2/5), and this week (1/4).
When you divide 140 by 2/5 by 1/4, you get 1400. Hope this helped!
