A solutions to a system of equations are the point where the lines intersect. There are four methods to solving systems of equations: graphing, substitution, elimination and matrices. Solving systems of equations is an important concept that shows up first in Algebra I, but is built upon in upper-level math.
Topics covered include: pre-algebra review, solving linear equations, graphing linear equations, inequalities, systems of linear equations, polynomials, factoring, rational expressions and equations, radicals, quadratics, and functions including exponential, logarithmic and trigonometric.

Graphing Utilities. Another way to solve inequalities is to graph the left hand side of the inequality as y 1 and the right hand side as y 2 and then find the intersection point. The intersection point will be your critical number. By looking at the graph, you can tell when the inequality is satisfied and record that interval.
The elimination method for solving linear systems Another way of solving a linear system is to use the elimination method. In the elimination method you either add or subtract the equations to get an equation in one variable.

Example 3: Graph the solution to 3(1 - 2x) x + 6. Solution : First you need to solve the inequality for x . Remember, you want to get x on the left side of the inequality, so once you distribute the 3, separate the variable by adding 5 x to and subtracting 3 from both sides.

Chapter 7: Systems of Equations and Inequalities Study Guide 7.1: Solve Systems of Equations by Graphing: - Be able to identify an ordered pair as a solution to a system Ex: Is (5, 2) a solution to the system: 2x – 3y = 4 2x + 8y = 11 No because if you plug in the ordered pair into both equations, it does not work.
6.1 Solving Inequalities in one variable Graph linear inequalities in one variable Solve linear inequalities in one variable Review Inequalities: Less than < x<5 Greater than > x>-2 Less than or equal to ≤ x ≤3 Greater than or equal to≥ x ≥0 To graph Inequalities: Use an open circle for < or > then shade the line in for which direction it will go.
Graphing Systems of Linear Inequalities: 1. Solve for y. (Don’t forget to flip the symbol if you multiply or divide by a negative number.) 2. Graph ALL the inequalities on the same coordinate plane. Remember: y < mx + b dotted and shaded below y > mx + b dotted and shaded above y 6mx + b solid and shaded below y mx + b solid and shaded above 3.
When solving systems of linear inequalities (or simultaneous inequalities): Step 1: Solve each inequality separately Step 2: Find the common values between the two inequalities. (Use a number line if necessary) Example: Solve the following simultaneous inequalities and represent your solution set on the number line. x + 2 < 6 and x – 3 ...
Solving a System of Equations. Systems of linear equations take place when there is more than one related math expression. For example, in \(y = 3x + 7\), there is only one line with all the points on that line representing the solution set for the above equation.
