I am quite new to Mathcad. I love the program but have run into some problems that I cannot seem to figure out on my own.

My problem is with solving an equtionsystem.

The following equations are just two random ones that I know the answer to but do not know how to get the answer through Mathcad.

Equations
4x-y=12
y+2x=x+1

I cannot figure out how to to this. If anyone is familiar with mathcad, I would be very grateful for some help on this one.
