Number Patterns when counting by Tens
When you count by tens the numbers create a pattern. All the numbers end with a zero. The first digits are just like the numbers when you count (1, 2, 3, 4, 5, etc.). This pattern gives the numbers 10, 20, 30, 40, 50, etc.

Answer: No solution
Step-by-step explanation:
x + 2x +7 = 3x - 7
3x + 7 = 3x - 7
3x + 7 - 7= 3x - 7 - 7
3x = 3x - 14
3x - 3x = 3x - 14 - 3x
0 = -14
The sides are not equal so there is no soulution.
