Simultaneous equations have the same values. Simultaneous Equations  sounds a bit daunting! The subject is not as fearsome as the title suggests. Play the following Math quiz a few times and read the helpful comments  you will soon find simultaneous equations are a doddle!














The correct answer is double the original expression. Each term in the expression has been multiplied by two and therefore 2x becomes 4x, 3y becomes 6y and 13 becomes 26

Here we took the original expression and multiplied each term by three. As long as we multiply each term by the SAME number, the letters in the resulting expression will always have the same value as those in the original expression


We would then have 4x + 6y = 38. The y's in each equation would then match and we would then say that the y's are 'balanced'

We would then have 8x + 2y = 42. The x's in each equation would be balanced


Because the balanced terms (6y) are both positive, we take one from the other to cancel them out and we are then left with a value for x

This time we have balanced the x terms and when we take one equation from the other we are left with a value for y. If one value for x had been positive and the other value for x had been negative we would ADD the equations together






That is as difficult as it gets in middle school math. If you got all the answers right in this quiz then you have mastered the subject!
