Solving One-Step Equations
... Example 1: Change y = 3/2x – 5 to Standard Form (Ax + By = C) – 3/2x + y = (3/2x) – (3/2x) – 5 – 3/2x + y = -5 This is negative and a fraction, so it is not yet in standard form. (-2)(-3/2)x + (-2)y = -5(-2) -3x -2y = 10 Example 2: Change y = 1/5x – 1 to Standard Form (Ax + By = C) – 1/5x + y = (1 ...

... The main command to solve equations is solve: [> equ := a^2*(x^2+x+1)-a*(2*x-3)-x^2-3*x+2; [> sols := solve(equ,x); Maple returns us two roots, but we have to be careful: the denominator in the solutions may vanish. We investigate what the equation looks like for this special parameter value: [> equ ...
