Find integers A and B such that (4,1) and (-5,-3) are solitions to Ax + By = 7
Plug them into x and y to get:
4A + B = 7
-5A + -3B = 7
try putting the coefficients and answers into a matrix and Row reduce....
oh... sorry, just finished a semester in Linear Algebra :-)
but really... you have 2 equations that are equal to each other ad 2 unknowns... that is easy to solve just read the math book you have (I know, I know who reads a math book :-D )
