Answer: The number you are thinking is 1
Solution:
Let the number you are thinking be = x
Multiplying the number by 7 = 7x
Adding the number 2 = 7x + 2
Multiplying the number by 2 = 2x
Adding the number 7 = 2x +7
Both these equation are equal to one another
7x + 2 = 2x + 7
Simplify the equation,
7x - 2x = 7 - 2
5x = 5
x = 1
