Question

incorrect
your answer is incorrect.
solve for u.
\\(\frac{u}{4} - 2.1 = -14.9\\)
your answer
u = 51.2

Explanation:

Step1: Add 2.1 to both sides

$\frac{u}{4} - 2.1 + 2.1 = -14.9 + 2.1$
$\frac{u}{4} = -12.8$

Step2: Multiply by 4 on both sides

$\frac{u}{4} \times 4 = -12.8 \times 4$

Answer:

$u = -51.2$
