Question

Solve for x.

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

Answer 1

should the answer be in terms of b

Answer 2

yes

Answer 3

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

Answer 4

can you solve
4x-4b= x ??
subtract x from both sides of the equation
add 4b to both sides of the equation.
