Work Step by Step

We are trying to isolate $x$ in the equation $4(x-b)=x$ First, we must use the distributive property to expand the left side: $4x-4b=x$ Then, we must subtract $4x$ from each side to get all of the $x$ terms together: $-4b=x-4x$ Next, we combine the $x$ terms by subtraction: $-4b=-3x$ Finally, we divide by $-3$ on both sides of the equation: $\frac{4b}{3}=x$
