Let the first and second number be x and y respectively
The first step is to interprete the problem using mathematical symbols
From the first statement, we have:
[tex]\text{ x + y= 36}[/tex]From the second statement, we have:
[tex]2x\text{ - y = 6}[/tex]So, we have the system of linear equations:
[tex]\begin{gathered} x\text{ + y = 36} \\ 2x\text{ - y =6} \end{gathered}[/tex]The next step is to solve the system of equations simultaneously
Adding equation 1 to 2:
[tex]undefined[/tex]
