Given the equation:
[tex]2x+10=28[/tex]to solve for x, first we have to move the constant 10 to the right side of the equation. When we do this, we have to change its sign to a negative sign:
[tex]\begin{gathered} 2x+10=28 \\ \Rightarrow2x=28-10=18 \\ 2x=18 \end{gathered}[/tex]Now we can divide both sides of the equation by 2 to get the following:
[tex]\begin{gathered} \frac{1}{2}(2x=18)\Rightarrow\frac{2}{2}x=\frac{18}{2}=9 \\ \Rightarrow x=9 \end{gathered}[/tex]therefore, x = 9
