Given the numerical equation:

16 = 9 + x

Solve for x.

Solution:

In order to solve for x, we simply need to transpose 9 on the other side of the equation, hence it must be taken to note that in transposing a number, the sign changes.

16 = 9 + x

x = 16 - 9

x = 7

Check:
9 + 7 = 16
16 = 16

Final answer
x = 7
