Question

Solve for x.

4(x – b) = x  i don't get how to do it i have tried i just dont understand

anonymous · Answer

should the answer be in terms of b

anonymous · Answer

yes

phi · Answer

First, use the distributive property:  4(a+b) is the same as 4*a+4*b  For example,
4(2+3)= 4*2+ 4*3= 8+12= 20
or
4(5)= 20
in your case:
4(x-b)=x 
you get: 4x-4b=x

phi · Answer

can you solve 4x-4b= x ?? subtract x from both sides of the equation add 4b to both sides of the equation. If this does not make sense, watch this http://www.khanacademy.org/video/simple-equations?playlist=Algebra and the next 2 after it.
