Subtract
What is (8m-3n) subtracted by (m-9)?
[tex] \\ = \tt(8m-3n) - (m-9) \\ [/tex]
Firstly, distribute the negative sign in the given equation.
[tex] \\ \tt = 8m−3n+ \red− \red1(m−9) \\ = \tt8m+−3n+ \red− \red1m+( \red− \red1)(−9) \\ \tt = 8m+−3n+−m+9 \\[/tex]
After distribution of negative sign, we combine like terms to get the final answer.
[tex] \\ \tt = 8m+−3n+−m+9 \\ = \tt(8m+−m)+(−3n)+(9) \\ = \begin{gathered} \boxed{ \large \boxed{\tt{7m−3n+9}}} \end{gathered} \\ [/tex]
- The final answer is 7m – 3n + 9.
