Following Steve's explanation, you can also have an increase by over 100%. For example, a price could increase by 200% - if the original price was $200 and then doubled to $400. This is possible because the original price was $200 - so 100% of the price is $200. When it ...

All you have to do in this situation is substitute (-2) for the variable (x) in the equation. You can do this because all coordinates are of the form (x,y). Anything in the place of (x) can be seen as equal to (x). So, substituting, we can see: 2(-2) - 3y = 5 -4 - 3y = 5 -3y...

**MATH**

Here, all you have to do is simply substitute (3) for the variable (x) in the equation. You can do this because all coordinates are of the form (x,y), and anything that takes the place of (x) in that form can be seen as equal to (x). The working is shown below: y = 2(3) + 4 y...

**MATH**

Here, all you have to do is substitute (7) for (y) in the equation. You can do this because all coordinates are of the form (x,y), and any number that is in the place of (y) in this format can be seen as equal to (y). The working is shown below: 5x - (7) = 3 5x = 10 x = 2 As ...
