Question

solve for u.
u - - 1.82 = 4.82
u =

Explanation:

Step1: Simplify the double - negative

The equation $u-(-1.82)=4.82$ simplifies to $u + 1.82=4.82$ because subtracting a negative number is the same as adding a positive number.

Step2: Isolate the variable $u$

Subtract 1.82 from both sides of the equation: $u+1.82 - 1.82=4.82 - 1.82$.
$u=4.82 - 1.82$
$u = 3$

Answer:

$3$
