Question

3x + 4 - 5x = 9 + 7x + 14

Answer 1

$\Large\displaystyle\begin{gathered} \sf{3x+4-5x=9+7x+14 } \end{gathered}$

$\Large\displaystyle\begin{gathered} \sf{ 3x-5x-7x=9+14-4} \end{gathered}$

$\Large\displaystyle\begin{gathered} \sf{ -9x=19} \end{gathered}$

$\Large\displaystyle\text{ \begin{gathered} \boxed{\boxed{\sf{ x=-\frac{19}{9}} }}\end{gathered} }$
