Question

solve for u.
3(u - 7) = 3
u =
submit

Explanation:

Step1: Expand the left - hand side

$3(u - 7)=3u-21$, so the equation becomes $3u - 21=3$.

Step2: Add 21 to both sides

$3u-21 + 21=3 + 21$, which simplifies to $3u=24$.

Step3: Divide both sides by 3

$\frac{3u}{3}=\frac{24}{3}$, so $u = 8$.

Answer:

$8$
