... The customary real numerical methods give approximations, not solu tions! The error of them is in general not known. It may be very large in particular cases, unknown to the user of such methods. Compared with this the interval methods have the big advantage to give always guaranteed bounds to the ...

elimination method
... What can we multiply by so that either the x or y value disappears? The top equation can be multiplied by 4 and the bottom equation by 3 to end up with 12x and –12x. When added together the x’s disappear. Solve for y. 12x + 20y = 24 (multiplied by 4) -12x + 6y = 15 (multiplied by 3) 26y = 39 (combin ...

ALGEBRA II 2A.3D Supporting
... For example, consider the system given by the equations 4x + 2y = 25 and y = -0.5x2 + 3x. Suppose a student estimates that the system has a solution at (5, 2.5). The first strategy to determine the reasonableness of this solution is to evaluate each equation at the given values of x and y. Here, 4(5 ...
