13-4x=1-x
First,I would move my x's to the right and my numbers to the left so...

13-4x=1-x
+4x +4x
-------------------
13=1+3x
-1 -1
----------------
12=3x

Now, you would divide 3 from both sides.

12=3x
---- ----
3 3
Solution: 4=x

To check the solution, plug in 4 for x.
13-4(4)=1-4
13-16=-3
-3=-3

The solution works, therefore
x=4

Add 4x to both sides and get
13 = 1 + 3x
12 = 3x [from subtracted 1 from both sides]
x = 4 [from dividing 3 from both sides]

therefore your answer would be x = 4

(m^-4/3)^1/4 divided by m^0 n^3/4(m^-3/2 n^2)

$\frac{(m^{-\frac{4}{3}})^{\frac{1}{4}}}{m^{0}(m^{-\frac{3}{2}}n^{2})} = \frac{m^{-\frac{1}{3}}}{m^{-\frac{3}{2}}n^{2}} = \frac{m^{\frac{3}{2}}}{m^{\frac{1}{3}}n^{2}} = \frac{m^{\frac{7}{6}}}{n^{2}} = \frac{\sqrt[6]{m^{7}}}{n^{2}} = \frac{\sqrt[6]{m^{6} * m}}{n^{2}} = \frac{\sqrt[6]{m^{6}}\sqrt[6]{m}}{n^{2}} = \frac{m\sqrt[6]{m}}{n^{2}}$
