3(x+4)-2(2+2x)=3(x-6+12+2)
3x+12-4-4x=3x-18+36+6
-x+8=3x+42-18
-x+8= 3x+24
-x-3x=-8+24
-2x=16
x=-8
Respuesta:
x = -4
Explicación paso a paso:
3(x+4)-2(2+2x)=3(x-6+12+2)
3x + 12 - 4 - 4x = 3x - 18 + 36 + 6
3x - 4x + 12 - 4 = 3x - 18 + 36 + 6
-x + 12 - 4 = 3x - 18 + 36 +6
-x + 8 = 3x - 18 + 36 + 6
-x + 8 = 3x + 18 + 6
-x + 8 = 3x + 24
-x - 3x = 24 - 8
-4x = 16
x = 16/-4
x = -4
