Question

Solve the equation3x+4=12x-1

Answer 1

`x=(5)/(9)`

Step-by-step explanation

`3x+4=12x-1`

Step 1

subtract 3x in both sides

`\begin{gathered} 3x+4=12x-1 \\ 3x+4-3x=12x-1-3x \\ 4=9x-1 \end{gathered}`

Step 2

add 1 in both sides

`\begin{gathered} 4=9x-1 \\ 4+1=9x-1+1 \\ 5=9x \end{gathered}`

Step 3

divide both sides by 9

`\begin{gathered} 5=9x \\ (5)/(9)=(9x)/(9) \\ x=(5)/(9) \end{gathered}`
