how to solve these equations::plz help

Dear mathcad fans,

I would like to know how to solve these equations ?

x1 + y1=6

x2 + y2=9

x1 + x2 =8

y1 + y2 =7

Any idea how to get that?

Thank you in advance.

Mr. emad habeeb,

There is no guessing of the correct values.

It is solved using the Mathcad's Matrix method.

Just try doing it.

Insert a matrix of 4 row and 1 column. Type the equation. x1+y1 (ctrl+=)6 ....complete the matrix.

After completing the matrix, use the symbolic keyword toolbar and click solve.

again insert the matrix of 4 row and 1 column and write the values x1, x2....etc.

You will finally get what is shown above.
