Answer: x = -1 and y = 9
The two equations are:
-9x + 2y = 23
-4x -y = -3
Now find for x in the first equation...
-9x + 2y = 23
-9x = 23 - 2y
x = (23 - 2y)/-9
Now place this value of x in the second equation and find for y...
-4{(23-2y)/-9} - y = -3
-92 + 8y + 9y = -3 * -9
17y = 27 + 92
y = 119/17
y = 7
Now place the value of y in the first equation," -9x + 2y = 23 " and find x
-9x + 2*7 = 23
-9x + 14 = 23
-9x = 23-14
x = 9/-9
x = -1
There you go! Hope it helps

Answer:
If x+8 is a factor, divide by -8.
-8 1 18 80
-8 -80
_______________
1 10 0
It is a factor because there is no remainder.
Step-by-step explanation:
Answer:
-16/15
Step-by-step explanation:
ok let's break this down.
6(4+7k) = 6*4 + 42k (use distributive property)
3k - 6(4+k) = 3k - 24 - 6k (do the same thing)
24 + 42k = 3k - 24 -6k (let's simplify this a bit)
24+42k = -24-3k (add 3k on both sides)
24+45k=-24 (subtract 24 on both sides)
45k = -48
k = -48/45 or -16/15
