Question

Solve the compound inequality.2u+6<18

Answer 1

Given:

An inequality 2u+6<18

To find:

We have to solve the given inequality.

Solution:

Subtract 6 from both sides to get:

$\begin{gathered} 2u+6-6<18-6 \\ 2u<12 \end{gathered}$

Divide by 2 both sides:

$\begin{gathered} \frac{2u}{2}<\frac{12}{2} \\ u<6 \end{gathered}$

Thus, the solution to the inequality is u < 6.
