Given:
The expression is
[tex]-\dfrac{3}{7}+\left(-\dfrac{3}{4}\right)[/tex]
To find:
The simplest form of given expression.
Solution:
We have,
[tex]-\dfrac{3}{7}+\left(-\dfrac{3}{4}\right)[/tex]
[tex]=-\dfrac{3}{7}-\dfrac{3}{4}[/tex]
Taking LCM, we get
[tex]=\dfrac{(-3)\times 4+(-3)\times 7}{28}[/tex]
[tex]=\dfrac{-12-21}{28}[/tex]
[tex]=\dfrac{-33}{28}[/tex]
Therefore, the simplified form of given expression is [tex]\dfrac{-33}{28}[/tex].
