Given the following System of equations:

[tex]\begin{cases}Y=5x-10 \\ Y=3x+8​\end{cases}[/tex]

You need to follow the steps shown below in order to find the solution:

Step 1. Set the equations equal to each other:

[tex]5x-10=3x+8[/tex]

Step 2. Solve for the variable "x":

[tex]\begin{gathered} 5x-3x=8+10 \\ 2x=18 \\ \\ x=\frac{18}{2} \\ \\ x=9 \end{gathered}[/tex]

Step 3. Substitute the value of "x" into any original equation and evaluate, in order to find the value of the other variable. This is:

[tex]\begin{gathered} Y=5x-10 \\ Y=5(9)-10 \\ Y=45-10 \\ Y=35 \end{gathered}[/tex]

The point is:

[tex](9,35)[/tex]

Then, the solution is:

[tex]\begin{gathered} x=9 \\ Y=35 \end{gathered}[/tex]
