What is the value of \(\large\rm |\color{royalblue}{x}|+\color{orangered}{y}\) when \(\large\rm \color{royalblue}{x=-3}\) and \(\large\rm \color{orangered}{y=15}\). \[\large\rm |\color{royalblue}{-3}|+\color{orangered}{15}\]\[\large\rm 3+\color{orangered}{15}\]

I still can't figure out where your 12 is coming from :)

12 is one of the answers

But why are you referring to that number at all? Just plug in the -3 and the 15.

|-3| + 15 simplies to 3 + 15

Anything in the absolute value signs becomes positive, |-2|=2, |-x|=x you see?

Ok I see where I went wrong. It is x+y not x+y=15. So 3+15 = 18. I looked at the equation wrong. Thank you,
