Question

1- (2x+5)/2+1=8
determina el valor de x
2. x/8-x/12=2

Answer 1

Explicación paso a paso:

1- (2x+5)/2+1=8

(2x+5)/2+1=8

[(2x + 5)/2] + 1 = 8

(2x + 5) +2 = 8.2

2x + 5 = 16 - 2

2x + 5 = 14

2x = 14 - 5

2x = 9

x = 9/2

x = 4,5

determina el valor de x

2. x/8-x/12=2

12(2x) - 8.x = 2

24x - 8x = 2

16x = 2

x = 2/16. = 1/8

x = 0,125
