Lesson Types Of Systems Inconsistent Dependent Independent
Solution Worksheet Solving Problems Involving Linear Inequalities This lesson concerns systems of two equations such as 2x y 10 3x y 13 The equations can be viewed algebraically or graphically Usually the problem is to find a solution for x and y that satisfies both equations simultaneously Graphically this represents a point where the lines cross There are 3 possible outcomes to this shown here in blue green and red
SOLUTION X y 10 x y 20 Find The Value Of X y Algebra , You can put this solution on YOUR website From x y 10 x y 20 let us solve for x in the first equation and substitute it into the second equation x 10 y then 10 y y 20 10y y 2 20 now solve y 2 10y 20 0 y 2 10y 20 0 Since this doesn t factor we can use the quadratic formula y 10 sqrt 100 80 2 y 10 2sqrt 5 2 y 5 sqrt 5 These are your Solution Worksheet Solving Problems Involving Linear Inequalities
