Given:

x + 45^3 = 81125

Determine the value of x.

Solution:

In order to solve for the value of x we simply need to take the cube of 45 and transpose it to the other side of the equation, note that when transposing a number the sign changes.

x + 45^3 = 81125

x +  91125 = 81125

x =81125 -91125

x = -10000

Final answer:

x = -10000
