-4<= (2k-1)/3 <= 2

- 4 \leq \frac{2 k - 1}{3} \leq 2

- \frac{11}{2} \leq k \leq \frac{7}{2}

Interval Notation

[- \frac{11}{2}, \frac{7}{2}]

Decimal Notation

- 5.5 \leq k \leq 3.5

Solution steps

- 4 \leq \frac{2 k - 1}{3} \leq 2

a \leq u \leq b

then

a \leq u and u \leq b

- 4 \leq \frac{2 k - 1}{3} and \frac{2 k - 1}{3} \leq 2

- 4 \leq \frac{2 k - 1}{3} : k \geq - \frac{11}{2}

\frac{2 k - 1}{3} \leq 2 : k \leq \frac{7}{2}

Combine the intervals

k \geq - \frac{11}{2} and k \leq \frac{7}{2}
