How to use if else expression to assign different variable name in scala

I'm trying to assign a different variable name for each value returned from the if else expression. This is because I want to use the return value later in my program and how to use it depends on which branch (if or else) is executed.

for example;

if(5<1) {val x = 5;x} else {val y = 1; y}

current output:

res31: Int = 1

Desired output:

y: Int = 1

Thanks
