Some input from you would be really nice

Hi

Here's one to get you started.

2x-11=13
add 11: 2x=24
divide by 2: x=12

Now you try the rest and tell us where you get stuck :-)

ii) x= 3/10

iii) x=66

iv) x=???

**Unknown008** · October 27th 2010, 08:21 AM

Right. For this one, one way of removing all the fractions is to multiply everything by the least common denominator.

$\dfrac{x}{4}- 1 = \dfrac23 + x$

Multiply by 12;

$3x- 12 = 8 + 12x$

Now, bring all the x on one side and the rest on the other side. Can you complete it now?

I need to spend some time going over it all, but cheers.
