Answer:
Step-by-step explanation:
Let 
be the greater number and 
be the smaller number. We know that their difference is 15, so we have
Then, we have the following information: if we add twice the greater (2x) and 8 (2x+8), the result is 3 times the lesser (3y) minus four (3y-4). So, we have
So, we have the follwing system:
From the first equation, we can derive 
, and substitute this expression in the second equation to get
Substitute this value for y in the first equation to get
its just 0...
Thats all its -1+1 so it would equal zero
Think about it like this
-1+1 = 1+(-1)
and when you add a negative what are you doing? Subtracting!
so 1-1 equals...?
0
6.5 x 10 to the 10th power.
10:00
11:00
1:00
2:00
Those are a few of the times :)
First distribute -2 to both x and -5
-2(x) = -2x
-2(-5) = 10
2x + 10 = -2x + 10
False. 2x + 10 ≠ -2x + 10
False is your answer
hope this helps
