The value of given expression $\frac{20}{-25+x}-2(x-10)$ at x = 5 is 9.

Step-by-step explanation:

Given expression $\frac{20}{-25+x}-2(x-10)$

We have to find the value given expression at x = 5.

Consider the given expression $\frac{20}{-25+x}-2(x-10)$

To find the value at x= 5 , put x = 5 in expression , we have,

$\Rightarrow \frac{20}{-25+5}-2(5-10)$

Solving , we get,

$\Rightarrow \frac{20}{-20}-2(-5)$

Simplify, we get,

$\Rightarrow -1+10$

$\Rightarrow 9$

Thus, the value of given expression $\frac{20}{-25+x}-2(x-10)$ at x = 5 is 9.
