Question

cuál es la ecuación de 1/4x+9=1/2x+8​

Answer 1

Respuesta:

-1/2

Explicación paso a paso:

1/(4x+9)=1/(2x+8)

2x + 8 = 4x + 9

+8-9 = 4x -2x

-1 = 2x

- 1/2 = x

Answer 2

Respuesta:

(1/4)x+9 = (1/2)x+8 ; m.c.m(2,4) = 4

4(1/4)x+4(9) = 4(1/2)x+4(8)

(4/4)x+36 = 2x+32

x+36 = 2x+32

x-2x = 32-36

-x = -4

-x/-1 = -4/-1

x = 4

Comprobación :

(1/4)(4)+9 = (1/2)(4)+8

(1(4)/4)+9 = (4(1)/2)+8

(4/4)+9 = (4/2)+8

1+9 = 2+8

10 = 10

R// X vale 4
