Solution

- 3 < 2 + 4 x < 12

Solution

- \frac{5}{4} < x < \frac{5}{2}

+2

Interval Notation

(- \frac{5}{4}, \frac{5}{2})

Decimal Notation

- 1.25 < x < 2.5

Solution steps

- 3 < 2 + 4 x < 12

If

a < u < b

then

a < u and u < b

- 3 < 2 + 4 x and 2 + 4 x < 12

- 3 < 2 + 4 x : x > - \frac{5}{4}

2 + 4 x < 12 : x < \frac{5}{2}

Combine the intervals

x > - \frac{5}{4} and x < \frac{5}{2}
