-7%283x-7%29%2B21x%3E=50 Start with the given inequality.


-21x%2B49%2B21x%3E=50 Distribute.


0x%2B49%3E=50 Combine like terms on the left side.


0x%3E=50-49 Subtract 49 from both sides.


0x%3E=1 Combine like terms on the right side.


0%3E=1 Simplify


Since the last inequality is NEVER true, this means that there are no solutions.
