2(x-1)+2 (x +1) = 6( x + 3 ) - 6 ( x + 1)



plissssss muchisimas gracias

Answer 1

2(x-1)+2 (x +1) = 6( x + 3 ) - 6 ( x + 1)
2x-2+2x+1=6x+18-6x-1
4x-1=17
4x=17+1
4x=18
x=18/4
x=9/2
Respuesta
x es igual a 9/2 ó 4 enteros 1/2

Answer 2

2(x-1)+2(×+1)=6(×+3)-6(x+1)
2x-2+2x+2=6x+18-6x-6
4x=12/:4
x=3

ahora si reemplazas x da:

2(3-1)+2(3+1)=6(3+3)-6(3-1)
2×2+2×4=6×6-6×4
4+8=36-24
12=12
