8%282x%2B4%29%2B7=4%284x%2B5%29%2B5 Start with the given equation.


16x%2B32%2B7=16x%2B20%2B5 Distribute.


16x%2B39=16x%2B20%2B5 Combine like terms on the left side.


16x%2B39=16x%2B25 Combine like terms on the right side.


16x=16x%2B25-39 Subtract 39 from both sides.


16x-16x=25-39 Subtract 16x from both sides.


0x=25-39 Combine like terms on the left side.


0x=-14 Combine like terms on the right side.


0=-14 Simplify.


Since this equation is never true for any x value, this means that there are no solutions.
