Hello here is a solution :
Answer:
(7,42)
Step-by-step explanation:
Imput the 6x for the Y:
6x=3x+21
move the variable to the left
6x-3x=21
collect like terms:
3x=21
divide both sides by 3x and youll get this for X
x=7
Imput x=7 into the equation
Y=6x7
solve:
y=42
It is D, because you have to get the denomenator"s equal so 9 times 4 is 36 and you take the numerator's and times by the other's denominator then subtract them to get 5/36

Answer:
x^(1/6)
Step-by-step explanation:
The applicable rule of exponents is ...
(a^b)/(a^c) = a^(b-c)
__
Here, we have a=X, b=1/2, c=1/3, so the quotient is ...
(X^(1/2))/(X^(1/3)) = X^(1/2 -1/3) = X^(1/6)
_____
Expressed as a radical, this is ...
![\displaystyle X^{\frac{1}{6}}=\sqrt[6]{X}](https://tex.z-dn.net/?f=%5Cdisplaystyle%20X%5E%7B%5Cfrac%7B1%7D%7B6%7D%7D%3D%5Csqrt%5B6%5D%7BX%7D)
