Question

Simplify the following algebraic expression.
$n-10+9n-3=0$

• A. $n=\frac{-13}{10}$
• B. $n=\frac{-13}{8}$
• C. $n=\frac{13}{10}$
• D. $n=\frac{13}{8}$

Answer 1

The correct option is C $n=\frac{13}{10}$

Let us simplify the given algebraic expression $n-10+9n-3=0$

$n-10+9n-3=0\Rightarrow (n+9n)+(-10-3)=0\Rightarrow 10n-13=0\Rightarrow 10n=13\Rightarrow n=\frac{13}{10}$

Hence, $n=\frac{13}{10}$.
