Solving Systems of Equations: Substitution Systems of equations can be solved by substituting an expression from one equation into the other equation. Examples: 1. 3 =2β4 = β + 9 Since y is equal to both (! β 4) (β + 9), those two expressions are equal to each other... 32 β 4 = β + 9 To solve the system, solve for x, and then substitute your solution for x into one of your original equations and solve for y. 2. = 2 β 1 3 + 2 = 6 Since y is isolated in the first equation, we can substitute "2 β 1" wherever we see y in the second equation: 3+22β1 =6 To solve this system, we can solve for x, and then substitute your solution for x into one of the original equations and solve for y.

To find the extreme values of a function f(x.y) on a curve x-x(t), y y(t), treat f as a function of the single variable t and use the chain rule to find where df/dt is zero. in any other single-variable case, the extreme values of f are then found among the values at the critical points (points where df/dt is zero or fails to exist), and endpoints of the parameter domain. find the absolute maximum and minimum values of the following function on the given curves. use the parametric equations x=2cos t, y 2 sin t functions: curves: i) the semicircle x4,y20 i) the quarter circle x2+y-4, x20, y20 b, g(x,y)=xy
