Answer:
x=2
y = 0
Step-by-step explanation:
3x + y = 6 -------------(i)
5x - 2y = 10 -------------(ii)
Multiply (i) by 2 ===> 6x +2y = 12
(ii) ===> <u> 5x - 2y = 10</u>
add ============> 11x = 22
x = 22/11
x = 2
Substitute x = 2 in (i)
3*2 + y = 6
6 + y = 6
y = 6 - 6
y = 0
1 and 3 only answer is number 2
Answer:
I <em>believe </em>it would be 4:7 books (the 4 new ones : the 7 older books).
Hope this helps!
Invert and multiply
2/x*(3/(4x))
Then proceed to simplify
(You must simplify twice might I add)
