Solve systems of two linear equations in two variables algebraically and estimate solutions by graphing the equations. By contextualising X and Y into something practical such as a cup of tea and a cup of coffee brings great success and improved confidence very quickly. A simultaneous equation has a general form which is written as ax by c.
Start recaps work on solving equations.
The difficulty is staggered in the main bit. Three part lesson on solving simultaneous equations where the coefficients of one variable is the same. Start recaps work on solving equations. The simultaneous equations are also known as the system of equations in which it consists of a finite set of equations for which the common solution is sought.
