# solving for 2 unknowns using 2 simultaneous equations

1. ## solving for 2 unknowns using 2 simultaneous equations

How is it that you do this. I have searched all over and can't seem to find
my computer froze up on me before I could read the post.

2. ## RE: solving for 2 unknowns using 2 simultaneous equations

Suppose the equations are 2x+3y=13 and x+5y=17. In cells A1, A2,B1 and B2
enter
2, 3, 1, 5. In cells D1 and D2 enter 13 and 17. Use the MINVERSE function in
cells F1 to G2 and enter A1:B2 as the array. In cells D6 and D7 use the
MMULT function and enter F1:G2 as the first array and D1:D2 as the second
array. It is important which one is first and which one second.
