Answer:

No solutions! :)

Step-by-step explanation:

To find the number of solutions in a problem we must solve it.

x+2x+7=3x-7

Firstly, combine common terms:

3x+7=3x-7

We can subtract 3x from both sides:

7=-7

The solution is 7=-7, which is no solution.

When a number is equal to a number in a solution, it has no solutions!
