Explicación paso a paso:
[tex]40 \times \frac{1}{2} + 38 \times \frac{1}{4} + 42 \times \frac{3}{4} + x = 150 \\ \frac{81 \times 2}{2 \times 2} + \frac{153}{4} + \frac{171}{4} + x = \frac{150 \times 4}{4} \\ \frac{162}{4} + \frac{153}{4} + \frac{171}{4} + x = \frac{600}{4} \\ \frac{486}{4} + x = \frac{600}{4} \\ x = \frac{114}{4} \\ x = 28 \times \frac{1}{2} [/tex]
