1. INEQUALITIES
1. An inequality is an algebraic statement involving the symbols >, <, ≥ or ≤
1. If x<2 There are infinitely many values that x could have. It can be shown on a number line like the one below.
1. On a number line if the circle is hollow it means that its not equal to the number and if the circle is filled in it means that it could also be the number its on.
1. When there is a pair of equations one is usually quadratic and the other is linear.
1. Equation 1: 2x + y = 7 Equation 2: 3x - y = 8
1. 2x + y = 7 3x - y = 8 ------------ 5x = 15 x = 3
1. Now you can put x = 3 in either of the equations. Substitute x = 3 into the equation 2x + y = 7: 6 + y = 7 y = 1 So the answers are x = 3 and y = 1
1. You can also show it in a graph
