Question

Resuelve cada ecuación X + 2/9=5/6, X + 5/2= 7, X+ 4 = 28/3, X - 1/4= 4/5 , 1/8 + X = 3/8

Answer 1

Explicación paso a paso:

$1) \\ x + \frac{2}{9} = \frac{5}{6} \\ \\ x = \frac{5}{6} - \frac{2}{9} \\ \\ x = \frac{45 - 12}{54} \\ \\ x = \frac{33}{54} \\ \\ x = \frac{11}{18}$

$2) \\ x + \frac{5}{2} = 7 \\ \\ x = 7 - \frac{5}{2} \\ \\ x = \frac{14 - 5}{2} \\ \\ x = \frac{9}{2}$

$3) \\ x + 4 = \frac{28}{3} \\ \\ x = \frac{28}{3} - 4 \\ \\ x = \frac{28 - 12}{3} \\ \\ x = \frac{16}{3}$

$4) \\ x - \frac{1}{4} = \frac{4}{5} \\ \\ x = \frac{4}{5} + \frac{1}{4} \\ \\ x = \frac{16 + 5}{20} \\ \\ x = \frac{21}{20}$

$5) \\ \frac{1}{8} + x = \frac{3}{8} \\ \\ x = \frac{3}{8} - \frac{1}{8} \\ \\ x = \frac{2}{8} \\ \\ x = \frac{1}{4}$
