How to work -1x-2y=-13 x-2y=11 equation by substitution
Norma-Jean [14]
Well if you're wanting to use substitution, you first have to end up with one term on either side of the equation. Use the second one as it's easiest. 

So: x-2y=11, so find -2y as there is a -2y in the first equation. 
then that becomes -2y=11-x. then sub that into equation 1, and you get:

-x+11-x=-13, which equals to -2x+11=-13, which is -2x=-24, so therefore

x=12. then chuck the x into any of the equations to find what y equals. 

hope this helps!

Following are the solution to the given question:

Step-by-step explanation:

Please find the complete question in the attached file.

H_0: \sigma^{2} \leq 0.0008\\\\H_a:  \sigma^{2} > 0.0008

The testing states value is:

\to x^2=\frac{(n-1)s^2}{\sigma^2}=32.6250

therefor the \rho - \ value = 0.2931

Through out the above equation its values Doesn't rejects the H_0 value, and its  sample value doesn't support the claim that although the configuration of its dependent variable has been infringed.
