Then my house will be in the south because thats the only one that is left
You have to plug in the numbers for x
X^2 + 2 = x + 8
x^2 - x + 2 - 8 = 0
x^2 - x - 6 = 0
Input 1 => 1^2 - 1 - 6 = 1 - 1 - 6 = -6
Input 3 => 3^2 - 3 - 6 = 9 - 3 - 6 = 0
Input 4 => 4^2 - 4 - 6 = 16 - 4 - 6 = 6
Input 5 => 5^2 - 5 - 6 = 25 - 5 - 6 = 14
Solution set { -6, 0, 6, 14}
Answer:
x=10,y=5,z=2
Step-by-step explanation:
x+15=2x+5
x=10
4y=8y-20
4y=20
y=5
10z-5=3z+9
