Question

What is the X coordinate to the solution of y =6x+9y = 12x -15?

Answer 1

The value of x is 4

Explanation:

We have the following system of equations

`\begin{gathered} y=6x+9 \\ y=12x-15 \end{gathered}`

Now, we solve the system by means of the equalization method

`\begin{gathered} 6x+9=12x-15 \\ \end{gathered}`

solving for x

`\begin{gathered} 12x-6x=9+15 \\ 6x=24 \\ x=(24)/(6) \\ x=4 \end{gathered}`
