Is there any way you could write this question a little more clearly?

Is it asking you to find x in each of those situations?

For example is it asking you to find the value of x when 4x-2= 0?
chloe
30 March 2011
If it is then we have to find out how to get x on its own
chloe
30 March 2011
so with
chloe
30 March 2011
we first have to add -2 to both sides so
chloe
30 March 2011
which gives us
chloe
30 March 2011
then to get x on its own we have to divide both sides by 4 so
chloe
30 March 2011
this then gives us
chloe
30 March 2011
We first have to add 3 to both sides giving us
chloe
30 March 2011
The same thing is going to be true for
chloe
30 March 2011
or
chloe
30 March 2011
Then we do the same thing as before, divide both sides by 6
chloe
30 March 2011
which gives us

With we can simplify this straight away by collecting all the xs together and collecting all the numbers together
chloe
30 March 2011
so
chloe
30 March 2011
Then we do the same as before, get the x on its own by adding 8 to both sides
chloe
30 March 2011
so then we have
chloe
30 March 2011
to get x on its own we divide both sides by 5 so
chloe
30 March 2011
which gives us
chloe
30 March 2011
to simplify 8/5 we ask ourselves how many times 5 goes into 8 which is 1 remainder 3 this gives us our final answer of x = 1 and 3/5

But I'm not sure if I've understood the question correctly so you might want to re-write it with some spaces in between
