Explanation
## Step 1: Solve the equation for
### The given equation is \( -54 = 6(u - 2) \). To find
, we first isolate
by performing the following steps:
Divide both sides by 6:
Add 2 to both sides:
## Step 2: Verify each value of
### We need to check if each given value of
(-4, -7, 1, 5) satisfies the equation \( -54 = 6(u - 2) \).### For
