3/ x -1 - 4 / x + 2=2
I work a bit backwards so, lets try looking at it like this,
3/ X
-4/X
what could X be to let these be positive since our outcome is positive?
3/0=0
4/0=0
so 3/0-1= -1
-1-4/0= 0
+2= 2
so 2=2
so now we go and fill it in to make sure
3/0-1-4/0+2=2
and it works so,
X= 0
I hope this helped some
Answer:
x=2ln(2)/(2ln(2)-ln(3))
Step-by-step explanation:
ln(4^x-1)=ln(3^x)
(x-1)ln(4)=ln(3^x)
(x-1)ln(4)=xln(3)
ln(4)x-ln(4)=xln(3)
ln(4)x=ln(3)x+2ln(2)
2ln(2)x-ln(3)x=2ln(2)
(2ln(2)-ln(3))x=2ln(2)
Therefore, x=2ln(2)/(2ln(2)-ln(3))
5. You can multiply 10 over 3 by the reciprocal of 2 over 3 to divide fractions. You get 30 over 6, and that simplifies to 5.
A ratios says how much of one thing there is compared to another thing and the trick with ratios is to always multiply or divide the numbers by the same value
