Question

12 + 2x - x = 9x + 4Solve the x

Answer 1

`12+2x-x=9x+4`

To solve the x:

1. Combine like terms:

2x+x=3x

`12+3x=9x+4`

2. Substract in both sides of the equation 9x:

`\begin{gathered} 12+3x-9x=9x-9x+4 \\ 12-6x=4 \end{gathered}`

3. Substract 12 in both sides of the equation:

`\begin{gathered} 12-12-6x=4-12 \\ -6x=-8 \end{gathered}`

4. Divide both sides of the equation into -6:

`\begin{gathered} (-6x)/(-6)=(-8)/(-6) \\ \\ x=(8)/(6) \end{gathered}`

5. Simplify:

`x=(4)/(3)`
