A Linear Equation is an equation for a line. A System of Linear Equations is when we have two or more linear equations working together.

Mash-up Math has a slew of these picture challenges that has a visual presentation of systems of equations. The objective of this activity is for students to solidify their knowledge of solving systems using substitution in a way that is engaging and requires student discourse. You will never be regret after getting this book. These particular worksheets allows for students to practice by using substitution on the first worksheet and the elimination method on the second worksheet.

System Of Equations Problems And Answers Pdf

Up to now we have solved equations with only one unknown variable. When solving for two unknown variables, two equations are required and these equations are known as simultaneous equations. The solutions are the values of the unknown variables which satisfy both equations simultaneously. We have two independent equations to solve for two unknown variables. We can solve simultaneous equations algebraically using substitution and elimination methods. We will also show that a system of simultaneous equations can be solved graphically.

Use the simplest of the two given equations to express one of the variables in terms of the other. Substitute into the second equation. By doing this we reduce the number of equations and the number of variables by one. Use the solution to substitute back into the first equation to find the value of the other unknown variable. This section can be included in the chapter on functions and graphs with graphs of linear equations.

Before beginning this section it may be necessary to revise plotting graphs of linear equations with your learners. It is also important that learners are either given the graphs or are encouraged to draw accurate graphs on graph paper to help them solve simultaneous equations graphically.

Graph sketching software can be used in this section to ensure that graphs are accurate. Simultaneous equations can also be solved graphically.

If the graphs of each linear equation are drawn, then the solution to the system of simultaneous equations is the coordinates of the point at which the two graphs intersect. We can also check the solution using algebraic methods.

You can use an online tool such as graphsketch to draw the graphs and check your solution. Sign up to get a head start on bursary and career opportunities. Use Siyavula Practice to get the best marks possible.
