Question

12) hallar el valor de la variable en cada ecuación.
$a. \: \times + \frac{3}{8} = \frac{7}{8}$
$b. \: m - \frac{1}{4} = \frac{5}{8}$ $c. \: x + \frac{3}{4} = \frac{1}{2}$
$d. \: \frac{5}{6} + \times = \frac{ - 2}{9}$
$e. \: t - \frac{1}{4} = \frac{1}{2}$
$f. \: x + \frac{1}{2} + \frac{1}{3} = \frac{7}{8}$
$g. \: x + \frac{5}{6} - \frac{1}{4} = 2$
​

Answer 1

Respuesta:

a) x = 1/2 b) m = 7/8 c) - 1/4 d) x = 19/18

e) t = 3/4 f) 1/24 g) 17/12

Explicación paso a paso:

a) x + 3/8 = 7/8

x = 7/8 - 3/8

x = 4/8 ====> x = 1/2

b) m - 1/4 = 5/8

m = 5/8 + 1/4

m = 7/8

c) x + 3/4 = 1/2

x = 1/2 - 3/4

x = - 1/4

d) 5/6 + x = - 2/9

× = - 2/9 - 5/6

x = - 19/18

e) t - 1/4 = 1/2

t = 1/2 + 1/4

t = 3/4

f) x + 1/2 + 1/3 = 7/8

x = 7/8 - 1/2 - 1/3

x = 1/24

g) x + 5/6 - 1/4 = 2

x = 2 -5/6 + 1/4

x = 17/12
