Sorry yet i do no longer think of your answer is incorrect. I presume you're increasing the brackets, so it fairly is the way I did it. (3x + 5) (x + 10) = 3x X x + 3x X 10 + 5 X x + 5 X 10 = 3x^2 + 30x + 5x + 50 = 3x^2 + 35x + 50

The answer to this is quite obvious if you think about it. If you pretend that x is not a number, but an object, say a computer. If you have 3 computers (3x) and you take away from those 3 computers 1 computer (x) you get 2 computers (2x). The answer hinges on the fact that x is the same as 1x, which makes the problem a lot easier.

3x - x = 2x. The way i thought of it was to always put a 1 infront of the 1. so essentially it reads 3x-1x. you know that x can equal anything....but aways the same thing so it will therefore read 3-1 which gives you 2.

3x-x=2x
Because you know that we can work out any number if it's same as the other number.They have to be identical.It mean, in this case 3x has x and other one also has a x.so these are identical .Like wise you can take away that 1x from 3x.So answer is 2x.

3x-x=x(3-1)
=x(2)
=2x

The easiest way to solve this is to factorise first.

So 3x - x = x(3 - 1) = x(2) = 2x

Hope this helps.
