X - y + z = -7
x + y + z = 1
-------------------add
2x + 2z = -6
x + y + z = 1
x + y - z = 9....multiply by -1
-------------------
x + y + z = 1
-x - y + z = -9 (result of multiplying by -1)
------------------add
2z = -8
z = -8/2
z = -4
2x + 2z = -6
2x + 2(-4) = -6
2x - 8 = -6
2x = -6 + 8
2x = 2
x = 1
x - y + z = -7
1 - y - 4 = -7
-y -3 = -7
-y = -7 + 3
-y = -4
y = 4
so x = 1, y = 4, and z = -4
Answer:
<h2>y > 12</h2>
Step-by-step explanation:
Answer:
$127.45
Step-by-step explanation:
First, subtract 450 from 3,508.80:
3,508.80 - 450 = 3058.8
Then, divide this by 24 to find the monthly payment:
3058.8/24
= 127.45
So, the monthly payment was $127.45
<u>24</u> = <u>30</u>
x = 100
<u>30x</u> = <u>2400</u>
30 = 30
x = 80
