The given equation is

[tex]2x-3=9[/tex]

To solve this equation we have to isolate x on one side and put the numbers on the other side

To do that we will add 3 to each side to move 3 from the left side to the right side

[tex]2x-3+3=9+3[/tex]

Simplify it

[tex]\begin{gathered} 2x+0=12 \\ 2x=12 \end{gathered}[/tex]

Now we need to move 2 from the left side to the right side, then

Divide both sides by 2

[tex]\begin{gathered} \frac{2x}{2}=\frac{12}{2} \\ x=6 \end{gathered}[/tex]

Then the solution of the equation is

x = 6
