Respuesta:

Rta:

1) x = 57/16

2) x = 215/11

Explicación paso a paso:

1)

(1/2) + (2x/3)*4 = 10

(1/2) + 8x/3 = 10

8x/3 = 10 - (1/2)

8x/3 = 20/2 - 1/2

8x/3 = 19/2

8x = [(3)(19)]/2

8x = 57/2

x = 57/(8)(2)

x = 57/16

2)

(2/4) + (3x/5) - (4/2) = 20 - (1x/2)

Reescribiendo:

(1/2) + (3x/5) - 2 = 20 - (x/2)

(3x/5) + (x/2) = 20 + 2 - (1/2)

Hagamos aparte:

(3x/5) + (x/2) = [2(3x) + 5(x)]/10 = (6x + 5x)/10 = 11x/10

Ahora:

20 + 2 - (1/2) = 22 - 1/2 = 44/2 - 1/2 = 43/2

Nos queda finalmente:

11x/10 = 43/2

11x = (10)(43)/2

11x = (5)(43)

11x = 215

x = 215/11
