10 < 2x+4 < 16.

Subtract 4 from all 3 parts of this compound inequality. You will get an equivalent compound inequality

6 < 2x < 12.

Now divide by 2 all 3 parts the last compound inequality. You will get an equivalent compound inequality

3 < x < 6.


It is your answer: The solution to the original inequality is this interval of the number line (3,6).

Solved.

Correct compound inequality: 10+%3C=+2x%2B+4+%3C=+16

Solve to get 3+%3C=+x+%3C=+6. This shows the range of values that satisfies the compound inequality.
