4%28b-1%29=-4%2B4b Start with the given equation.


4b-4=-4%2B4b Distribute.


4b=-4%2B4b%2B4 Add 4 to both sides.


4b-4b=-4%2B4 Subtract 4b from both sides.


0b=-4%2B4 Combine like terms on the left side.


0b=0 Combine like terms on the right side.


0=0 Simplify.


Since this equation is ALWAYS true for any b value, this means b can equal any number.

So there are an infinite number of solutions.
