Answer:
x=-1
Step-by-step explanation:
8/x+2=2/x-4
8/x=2/x-6

Answer:
Step-by-step explanation:
y-5/x+1 = -3/7
7(y-5)=-3(x+1)
7y-35=-3x-3
7y+3x-32=0
Answer:
(-4, -1/2)
Step-by-step explanation:
The endpoints of AB are (-5,-4) and (-3,3)
To find the midpoints add the endpoints and divide by 2
(-5+-3)/2, (-4+3)/2
-8/2, -1/2
-4, -1/2
the number is 6
let the number be n , then the difference of this number and 3 is n - 3
4 times this is 4(n - 3) = 12 ( solve for n )
divide both sides by 4
n - 3 = 3 ( add 3 to both sides )
n = 3 + 3 = 6
the number is 6
