In AND statements, the solution is the intersection of two sets of numbers. Essentially, you are looking for "common ground" or numbers that both sets share. These solutions can represent both betweenness and an alternate type of solution. To see the difference between these two types of solutions, perform the two problems below:

For each problem, graph the set of solutions that satisfy both equations. How are the solutions to these two problems different?

1) x+3__>__1 and x-1<3

2) 2x>4 and -2x__<__-8


 * answer** (i graphed out the solutions but i dont know how to put a number line on wikii)

1. x __>__ -2 and x<3

2. x>2 and x> 4 which means you can just write x>4 because its true for both statements.

these are different problems because one you find there is a limited number of answers between 2 numbers, but in the other one there are an infinite number of answers because the only restriction is that it must be greater than four. also they're different in taht you preform different operations to find x
