1. (3x+5)/2 - (4x+5)/3 = (7x+1)/6 - 5

Answer 1

(3x + 5)/2 - (4x + 5)/3 = (7x + 1)/6 - 5 [Multiplicamos por 6, para no tener fracciones]

6(3x + 5)/2 - 6(4x + 5)/3 = 6(7x + 1)/6 - 6(5)

3(3x + 5) - 2(4x + 5) = 1(7x + 1) - 30

9x + 15 - 8x - 10 = 7x + 1 - 30

9x - 8x + 15 - 10 = 7x + 1 - 30

x + 5 = 7x - 29

5 + 29 = 7x - x

34 = 6x

34/6 = x

17/3 = x

∴ x = 17/3

Answer 2

Respuesta:

X=29/6

Explicación paso a paso:

6.3x+5/2 - 6.4x-5/3=6.7x+1/6- 6.5

9x+5-8x-5=7x+1-30

9x-8x-7x=1-30-5+5

-6x= - 29

X= -29/-6

X=29/6
