Add like terms:
[tex]\begin{gathered} 2x+4=4x-10 \\ \end{gathered}[/tex]subtract 2x from both sides:
[tex]\begin{gathered} 2x+4-2x=4x-10-2x \\ 4=2x-10 \end{gathered}[/tex]Add 10 to both sides:
[tex]\begin{gathered} 4+10=2x-10+10 \\ 14=2x \end{gathered}[/tex]Divide both sides by 2:
[tex]\begin{gathered} \frac{2x}{2}=\frac{14}{2} \\ x=7 \end{gathered}[/tex]
