i think im right about this
1, 4, 9, 16, 25, 36, 49, 64, 81, 100
The answer is 5 and 18. This is because 5 times five is 25. 25 minus 7 is 18.

Are you trying to find x, or are you only suppose to translate it?
If you are trying to find x, you first multiply 2x on both sides
100 = 10(2x)
Divide 10 on both sides
10 = 2x
Divide 2 on both sides
5 = x
