Question

resolver la ecuacion dada y comprobar la respuesta
x-[4-(x+1)=4x-15

Answer 1

aqui esta ra respuesta corregi
da
(4-(x-1))=4-15
x-(4-x-1)=4-15
x-(3-x)=4x-15
x-3+x=4x-15
2x-3=4x-15
15-3=4x-2x
12=2x
6=x

Answer 2

x-[4-(x+1)]=4x-15
x-[4-1-x]=4x-15
x-[3-x]=4x-15
x+x-3=4x-15
2x-3=4x-15
2x-4x= -15+3
-2x= -12
x= -12/-2
x=6
....................................................................
x-[4-(x+1)]=4x-15
6-[4-(6+1)]=4(6)-15
6-[4-(7)]=24-15
6-[4-7]=9
6-[-3]=9
6+3=9
9=9
