7
-2
infinite number of solutions
no solution

Answer 1

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.
