    let \(x\) be our first number and \(y\) our second "One number is 25 more than a second number" \[x=y+25\] " The sum of these two numbers is 106." \[x+y=106\] Plug the first equation into the second equation for \(x\).

    i think you should not consider the other number as y coz u see the statement ,the other number is 25 more than the second number so,it should be x+25

    If you use the standard method you would name both variables \(x=y+25\) and \(x+y=106\) Plug in for \(x\) \((y+25)+y=106\) You will get the same answer...
