Standard 2.2.b:Solve systems of linear equations and inqualities using various methods.
A system of linear equations is where the solution is and it is also where the two lines intersect. As for inequality means finding all of the soulutions in the inequality. An inequality is a number which when substituted for the variable makes the inequality a true statement.

Below are two example problems. They range from easy to difficult.
 * Example Problems for Standard 2.2.b**

What is the solution to this system or equation? //3x - y + 5 = 0 2x + 3x- 4= 0// A) x = -1, y = -2 B) x = -1, y = 2 C) x = 2, y = -1 D) x = 2, y = 1** All you have to do to answer this problem is plug in the numbers for the variables, and which ever one gives you zero is your answer.
 * Problem 1-Example

//**x + y = 5 x + z = 7 y + z = 16
 * Problem 2- Example**
 * What is the solution to the system of equation?

A) {2, 3, 9} B) {2, 7, 5} C) { -2, 8, 8} D) {-2 ,7, 9}**//

All you have to do on this equation is the same thing as the other example..... Just replace the numbers for the letters, for example the first number in the bracket is you x, the second number is the y, and the third number is the z.
