Simultaneous Linear Equation Worksheets | Math Worksheets
Simultaneous equations models are a type of statistical model in which the dependent variables are functions of other dependent variables, rather than just independent variables. This means some of the explanatory variables are jointly determined with the dependent variable, which in economics usually is the consequence of some underlying equilibrium mechanism. For instance, in the simple model of supply and demand, price and quantity are jointly determined. Simultaneous equations, Maths GCSE revision looking at simultaneous equations and Linear equations. Solving them using elimination and substitution.� If an equation has two unknowns, such as 2y + x = 20, it cannot have unique solutions. Two unknowns require two equations which are solved at the sametime (simultaneously) ? but even then two equations involving two unknowns do not always give unique solutions. The video below works through examples of simultaneous equations. The step-by-step example shows how to group like terms and then add or subtract to remove one of the unknowns, to leave one unknown to be solved. This method is called solution by substitution.

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.
