So the aim of simultaneous equations like this, are to figure out the value of x and y. The first thing you have to decide is which one to figure out first. You have to make both 'x' values or both 'y' va...

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 ...

when multiplying indices you need to add the powers (only if the base number is the same -> need to ensure they are denoted with the same letter)

4 + 3 = 7

therefore the answer is c^7

First, you must remember what the midpoint formula is for a line with two points.

M= ((x_1​+x_2​)/2 ​,(y₁​+y_2​​)/2)

Then apply it to this question.<...

The first step would be to consider each of the powers individually, work out their value and then proceed with the subtraction to end up with a result. Firstly, as this question is to be done without a c...
