Systems Substitution Method Example 1
Here is an example of how to solve a system using the substitution method. Remember to read the lesson on this topic.
Basic steps to follow:
1. First understand that the solution to a system is the (x, y) point where the lines that make up the system intersect
2. Solve for one of the variables in one of the equations of the system
3. Substitute the results from step 2 into the other equation; this will result in a one variable equation that you can solve.
4. Use the solution from step 3 to solve for the other variable

Important habits to master math:
1. write out all steps
2. be very neat
3. use pencil not pen
4. review your work as your go
5. make sure you know the basics like fractions, positive and negative numbers and order of operations
Systems Of Inequalities Example 1
Here is an example of how to solve a system of inequalities. Remember to read the lesson on this topic.
Basic steps to follow:
1. First make sure you understand how to solve linear inequalities and systems
2. Graph both lines of the system and find the solution; be mindful of the lines you draw; < and > inequalities will have dashed lines and ≤ and ≥ will have solid lines
3. Test a the point (0, 0) for each inequality of the system and shade towards the true region; the overlapping shaded region of both lines indicates the solution of the system of inequalities
4. Students need to have mastered inequalities of two variables before systems of inequalities
