Do you mean like the place value? If you do then it would be in the ones place.
The answer is y'=1/(x-1).
Solution:
y=(x+1)/x
Switch all the x's with y's, and y's with x's.
x=(y+1)/y
xy=y+1
xy-y=1
y(x-1)=1
y'=1/(x-1)
Answer:
y = -4.174 (aprox)
x = 9.435 (aprox)
Step-by-step explanation:
-2x - 5y = 2 Eq. 1
x = -47 + 9y Eq. 2
substituying the Eq. 2 in the Eq. 1:
-2(-47+9y) - 5y = 2
(-2*-47 -2*9y) - 5y = 2
-94 -18y - 5y = 2
-23y = 2 + 94
-23y = 96
y = 96/-23
y = -4.174 (aprox)
from the Eq. 2
x = -47 + 9y
x = 47 + 9*-4.174
x = 47 - 37.565
x = 9.435 (aprox)
Check:
from the Eq. 1
-2x - 5y = 2
-2*9.345 -5*-4.174 = 2
-18.87 + 20.87 = 2
