Full solution

Q. Solve for

u

.

\newline

2u + 4 < 8

Subtract $4$ to isolate u: Step $1$ : Subtract $4$ from both sides of the inequality to isolate the term with u. $\newline$ 2u + 4 - 4 < 8 - 4 $\newline$ 2u < 4
Divide by $2$ to solve: Step $2$ : Divide both sides by $2$ to solve for $u$ .\frac{2u}{2} < \frac{4}{2}u < 2
