MATHCAD SIMULTANEOUS DIFFERENT EQUATION
I'm trying to solve a simultaneous differential equation.
Do I need to use a solve block (which is only available in the full version) to solve simultaneous differential equation and it would work?

DE or systems of DEs can only be solved numerically
You have to use a solve block or one of the standalone solvers (which I guess are also available in the full version only).
I added an arbitrary initial condition and I had to change the first equation as Prime choked on the one you provided. Not sure why but I guess that not both equations are allowed to include derivations of both functions. So I multiplied the first by 2 and subtracted the equations to get a new equivalent equation.

You don't necessarily need to use a solve block, if you're willing to do some math. But your problem description is not complete as Leopold also pointed out: initial conditions are missing.
It's very well possible that both solutions are equal. This first solution, with X0=0 and Y0=10, leads to:
Success!
