Solve the simultaneous equations 2x−3y=12 and 3x + 4y = 8

To solve this question we will first have to think of how we can solve something with two variables. The most common method is through elimination where we remove a variable so then we have an expression for the other. 

To do this we can multiply the first expression by 3 and the second expression by 2. This gives us 6x-9y=36 and 6x+8y=16 This means we now know that -17y=20 so y=-20/17 and then we can sub this value in to get x=72/17.
