Answer:
All solutions
Step-by-step explanation:
When solving by substitution, we will first set one equation equal to a variable, and then plug that value into the second equation as the variable. Here is what I mean;
x - 2y = 1
3x - 6y = 3
-
x = 1 + 2y
3x - 6y = 3
-
3(1 + 2y) - 6y = 3
3 + 6y - 6y = 3
3 = 3
[] Oh no! This doesn't work well. Let's graph it and see what is happening;
-> See attached
-> I have made the lines very thick so you can see the overlap, they are the same size in reality
The answer is all solutions because the graphs are exactly the same.
Have a nice day!
I hope this is what you are looking for, but if not - comment! I will edit and update my answer accordingly.

B = 1/4c + 14
d = 5/4c - 2
b = d
1/4c + 14 = 5/4c - 2 ....multiply by 4
c + 56 = 5c - 8
56 + 8 = 5c - c
64 = 4c
64/4 = c
16 = c <== Chris
b = 1/4c + 14.....b = 1/4(16) + 14.....b = 4 + 14....b = 18 <== Brian
d = 5/4c - 2....d = 5/4(16) - 2.....d = 20 - 2.....d = 18 <== Damien
solution : Brain and Damien answered 2 more questions correctly then Chris did. <===

Step-by-step explanation:
Cards: 1,2,3 total cards 3
P (3) = number of 3's / total cards
= 1/3
We keep the 3
Cards: 1,2 total cards 2
We want a card greater than 2
cards greater than 2 : 0
P (card >2) = cards greater than 2 / total cards
=0/2
P (3, no replacement, >2) = 1/3 * 0 =0
Answer:
A.
Step-by-step explanation:
If you take -6 and add 12, you first add 6 to make it zero, and have 6 to add after that. This gives you 6* F
