Presumably by setting all four equations to zero. However, look carefully at your "a" and "d" equations - they are incompatible. Both have identical coefficients for xa, xb etc. but they have different constant terms.

Thanks Alan.

Is there a better way of doing this?

I can use matrix solve simultaneous equations ???

thanks Alan

Yes, you can use a matrix approach to solve linear simultaneous equations.

hi Alan. Please help me.

I want caculation solve simultaneous equations of mathcad prime 2.0 ????? ( No solve Matrix)

Picture I slove why Faile??????????

You forgot the powers of ten! Always assign results to varaibles to avoid this problem.

See attached.

And here's an alternative solution method.
