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!
