Instructions given below
So there is a total of 2000 books, subtract 500 from that because thats how many childrens books there are. SO you have 1500, there are 200 more fiction books than nonfiction so that would mean there are 950 fiction books and 550 nonfiction books.
Question (1):
The first given equation is:
j + k = 3
This can be rewritten as:
j = 3 - k .................> I
The second given equation is:
j - k = 7 ............> II
Substitute with I in II and solve as follows:
j - k = 7
(3-k) - k = 7
3 - 2k = 7
-2k = 7-3 = 4
k = 4/-2
k = -2
Substitute with k in I to get the value of J as follows:
j = 3 - k
j = 3 - (-2) = 3+2
j = 5
Based on the above, the solution is (5,-2)
Question (2):
The first given equation is:
y = 2x - 6 .........> I
The second given equation is:
4x - 2y = 14............> II
Substitute with I in II and solve as follows:
4x - 2y = 14
4x - 2(2x - 6) = 14
4x - 4x + 12 = 14
12 = 14
Since this is not possible, therefore, the system has no solution
Question (3):
The first given equation is:
y = x - 8 .............> equation I
The second given equation is:
2x + 3y = 1 ..............> equation II
Substitute with equation I in equation II and solve as follows:
2x + 3y = 1
2x + 3(x - 8) = 1
2x + 3x - 24 = 1
5x = 25
x = 25/5
x = 5
Substitute with x in equation I to get y as follows:
y = x - 8
y = 5 - 8
y = -3
Based on the above, the solution of the system is (5,-3)
Hope this helps :)
