Is it possible to get the individual values out of a solution of an equation?
Like in the examples of linear equations:
12x + 13y = 163
-2x + 100y = 688
We can solve for x and y by taking the constants on the left hand side and putting them in a matrix:
a = [12, 13; -2, 100]
and by putting the right hand side into a vector:
b = [163; 688]
Now we can convert our two equations into one and solve for x and y:
a * xy = b
xy => [6; 7]
Now I would get x = 6 and y = 7, without copy/paste. With copy/paste you have to redo it when you change the equation above.
xy here looks like a matrix (column vector), but x = xy does not set x to 6. Is there some hidden or secret way to do it?
