3x%2B7-x=2x%2B21 Start with the given equation. 


2x%2B7=2x%2B21 Combine like terms on the left side. 


2x=2x%2B21-7 Subtract 7 from both sides. 


2x-2x=21-7 Subtract 2x from both sides. 


0x=21-7 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. 


So there are no solutions.
