Question

solve the equation n - 9/10 = - 109/10

Answer 1

to solve this question, we need to simplify

step 1

write out the equation and collect like terms

$\begin{gathered} n-\frac{9}{10}=-\frac{109}{10} \\ n=-\frac{109}{10}+\frac{9}{10} \end{gathered}$

step 2

take the LCM and solve the fraction

the LCM here is 10

$\begin{gathered} n=-\frac{109}{10}+\frac{9}{10} \\ n=\frac{-109+9}{10} \\ n=-\frac{100}{10} \\ n=-10 \end{gathered}$
