-9%2B4r=4r-3-6 Start with the given equation.


-9%2B4r=4r-9 Combine like terms on the right side.


4r=4r-9%2B9 Add 9 to both sides.


4r-4r=-9%2B9 Subtract 4r from both sides.


0r=-9%2B9 Combine like terms on the left side.


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


0=0 Simplify.


Since this equation is always true for any r value, this means r can equal any number. So there are an infinite number of solutions.
