1) Mathematical modelling of climate may employ basic understanding of simultaneous equations'. In this line, consider the three hypothetical "toy" simultaneous linear equations below: 3x + 2y + z = 11; 2x + 3y + z = 13; x + y + 4z = 12; (a) Solve for the value of x, y, and z which satisfy all the three simultaneous equations using either substitution or elimination method in college algebra. .. (b) Now, solve for the value of x, y, and z which satisfy the same simultaneous equations using Cramer's rule in matrix theory. Did you get the same results as in (a)? .
