6, I guess. 1 red and 6 green, 2 red and 5 green. 3 red and 4 green, 2 green and 5 red, 1 green and 6 red, 3 green and 4 red,
19 is a prime number so 1, 19
hope this helps!
Take the second equation and flip it around so the y on the left ends up on the right and the 4x on the right ends up on the left. This makes all negatives positive and all positives negative. -4x + 12 = y
Then add the first equation to the second equation
4x +12 = -7y
<u>-4x + 12 </u>=<u> y </u> this eliminates the x's
<u>24</u> = -<u> 6y</u> then divide by - 6
- 6 - 6
- 4 = y<u>
</u>So if you know that y = negative 4, you can substitute into either equation. I pick the second one because I am a lazy person.
-y + 12 = 4 x
-(-4) + 12 = 4 x combine your numbers<u>
</u> <u> 16 </u> = <u>4 x </u> then divide by 4<u>
</u> 4 = x
So your solution is: x = 4 and y = -4 or this is also written (4, -4)
Does that work for you?
<span>10p+5=18p-6/2
10p + 5 = 18p -3
10p - 18 p = -3 -5
-8p = -8
p = -8/-8
p =1</span>
