Solve for $u$ in the equation $9=u-8$ .

STEP 1

Assumptions
1. We are given the equation $9 = u - 8$ .
2. We need to solve for $u$ .

STEP 2

To solve for $u$ , we need to isolate $u$ on one side of the equation. We can do this by adding $8$ to both sides of the equation to cancel the $-8$ on the right side.
$u - 8 + 8 = 9 + 8$

STEP 3

Perform the addition on both sides of the equation.
$u = 9 + 8$

STEP 4

Calculate the sum on the right side of the equation.
$u = 17$
The solution to the equation $9 = u - 8$ is $u = 17$ .
