Question

0,12/3 = (x + 2)/(0, 3)


PORFAVOR ​

Answer 1

Explicación paso a paso:

0,12/3=(x+2)/0,3

12/100:3=(x+2):3/10

12*1/100*3=(x+2)*10/1*3

12/300=(x+2)*10/3

12=(x+2)*10*100

12=(x+2)*1000

12=1000x+2000

12-2000=1000x

-1988=1000x

x=-1988/1000=-1,988

Comprobamos

(-1,988+2)/0,3=0,012/0,3=0,04

Solución

X=-1,988
