Question

6x+9=2x+13 solve for x

Answer 1

The given equation is

`6x+9=2x+13`

First, we subtract 2x on each side.

`\begin{gathered} 6x+9-2x=2x-2x+13 \\ 4x+9=13 \end{gathered}`

Then, we subtract 9 on each side.

`\begin{gathered} 4x+9-9=13-9 \\ 4x=4 \end{gathered}`

At last, we divide the equation by 4.

`\begin{gathered} (4x)/(4)=(4)/(4) \\ x=1 \end{gathered}`

Therefore, the solution is 1.
