Simplify the difference.

mr_godi [17]

$\displaystyle\frac{n^2-10n+24}{n^2-13n+42}-\frac{9}{n-7}=\frac{(n-6)(n-4)}{(n-6)(n-7)}-\frac{9}{n-7}\\\\=\frac{n-4}{n-7}-\frac{9}{n-7}=\frac{n-4-9}{n-7}\\\\=\frac{n-13}{n-7}$

The last choice is appropriate.

Write three different equations that have x=5 as a solution

svlad2 [7]

Answer: The three different equations will be

$x+3=8\\\\2x-8=2\\\\4x-4=16$

Step-by-step explanation:

We have to write three equation that have x = 5 as a solution:

1) First equation will be

$x+3=8\\\\x=8-3\\\\x=5$

2) Second equation will be

$2x-8=2\\\\2x=8+2\\\\2x=10\\\\x=\frac{10}{2}\\\\x=5$

3) Third equation will be

$4x-4=16\\\\4x=16+4\\\\4x=20\\\\x=\frac{20}{4}\\\\x=5$

Hence, the three different equations will be

$x+3=8\\\\2x-8=2\\\\4x-4=16$
