Equations and Inequations
Equations and inequalities describe the relationship between two mathematical expressions.
Linear Functions
A linear function can just be a constant, or it can be the constant multiplied with the variable like x or y. If the variables are of the form, x2, x1/2 or y2 it is not linear. The exponent over the variables should always be 1.
Find three consecutive even intergers such that the product of two smaller numbers is the same as twice the sum of all three intergers

If x=-2, then the numbers are -2,-2+2,-2+4, that is -2,0,2
If x=6, then numbers are 6,6+2,6+4, that is 6,8,10
