Simultaneous equations like π’š = 2𝒙 - 1 and π’š = 𝒙 + 1 can be represented graphically. To solve the equations graphically, the two lines π’š = 𝒙 + 1 and π’š = 2𝒙 - 1 are drawn on the same diagram.
Make sure you are confident in calculating with negative numbers, which is a skill often needed to solve equations. To solve the equation, do the inverse operation. The inverse of multiplying by 12 is ...
It’s time to answer the age-old question of who would win between an Olympic sprinter, tortoise, car, you, and a volcano. Linear equations can be used to roughly see how you and other creatures stack ...
