Here’s Mr Eddie Woo, solving simultaneous equations for his students. 


When do I use the elimination or substitution method in mathematics paper?

The answer to this question is – if the coefficient of any variable is 1, which means you can easily solve for it in terms of the other variable, then substitution is a very good bet.

If all the coefficients are anything other than 1, then you can use elimination, but only if the equations can be added together to make one of the variables disappear. You can make use of common multiples to get rid of one of the variables to solve for the other.


Additional practice for simultaneous equations 

Remember to pace yourself because knowing how to manage your time is as crucial as getting these answers correct.

Additionally, you can also use this website to help you find the answers by keying in the equations.


Tips for doing simultaneous equations in mathematics paper

1 – label your equations when using the substitution method 

2 – for the elimination method, it might be easier to know the common multiple of the two equations 

3 – always be careful and pay extra attention to the operations, and make sure your pluses become minuses when you bring them over from one side of the equation to the other


In a nutshell, simultaneous equations in mathematics paper are easy to get a hang of when you keep practising. As you continue to practice more, you will build muscle memory around it and these methods will come to you naturally.
