ANSWER
x = -9
EXPLANATION
To solve this equation, first, we have to add like terms,
[tex]\begin{gathered} (5x-14x)+(-2-3)=(5x-10x)+31 \\ \\ -9x-5=-5x+31 \end{gathered}[/tex]
Then, add 9x to both sides of the equation,
[tex]\begin{gathered} 9x-9x-5=9x-5x+31 \\ -5=4x+31 \end{gathered}[/tex]
Subtract 31 from both sides,
[tex]\begin{gathered} -5-31=4x+31-31 \\ -36=4x \end{gathered}[/tex]
And divide both sides by 4,
[tex]\begin{gathered} \frac{-36}{4}=\frac{4x}{4} \\ -9=x \end{gathered}[/tex]
Hence, the solution is x = -9.
