To answer this question you need to group the different terms to form the shortest equation possible. It is easiest to treat the x terms and the y term as seperate, so you have:

2x - x      and    ...

The question is asking you to isolate, or find out what 'x' is in relation to the equation. Don't be confused by the less than sign '<'. Treat it like an equals sign '='. 3x - 5 =16.

So let's ge...

The first step is to expand the brackets on the left hand side, you can either use the arrow method or the box method for this. This gives you: 6x + 24 = 2x - 4

Then you want to gather all the x's ...

The nth term of a sequence means that when we substitute the value of n in to the equation, we find that term. So to find the 4th term in the sequence, we substitute 4 in for n. 7(4)-4=28-4=24. The 10th t...

To find the median, we first need to rewrite the set of data in ascending order of values: 2, 16, 16, 34, 43, 43, 55, 62, 91. We then count how many items are in this list. The median is the item in the m...
