Question

ayudenme con estas ecuaciones com proceso

1/2 - 4 + 7/12x + 3/5x = -3 + 31/60x

1/16x + 7/2 + ( 1 - 14/16 ) x - 1/6 + 2/32x = 43/12

Answer 1

$\frac{1}{2} - 4 + \frac{7}{12} x + \frac{3}{5} x = - 3 + \frac{31}{60} x \\ - \frac{7}{2} + \frac{7}{12}x + \frac{3}{5} x = - 3 + \frac{31}{60} x \\ - 210 + 71x = - 180 + 31x \\ 71x - 31x = - 180 + 210 \\ 40x = 30 \\ x = \frac{3}{4}$

$\frac{1}{16} + \frac{7}{2} + (1 - \frac{14}{16}) \times( - \frac{1}{6}) + \frac{2}{32}x = \frac{43}{12} \\ \frac{1}{16} + \frac{7}{2} + \frac{1}{8} \times ( - \frac{1}{6} ) + \frac{1}{16} x = \frac{43}{12} \\ \frac{1}{16} + \frac{7}{2} - \frac{1}{48} + \frac{1}{16} x = \frac{43}{12} \\ \frac{85}{24} + \frac{1}{16} x = \frac{43}{12} \\ 170 + 3x = 172 \\ 3x = 172 - 170 \\ 3x = 2 \\ x = \frac{2}{ 3}$

Answer 2

Hola !!!

Respuestas:

1) x= 3/4

Comprobación :

40x=30

Reemplazamos "x" :

40(3/4) =30
10*3 =30
30=30

2) x=1

24x + 320 =344

Reemplazamos "x" :

24(1) + 320 = 344
24 +320 =344
344 =344

Espero te sirva !! ^^
