Respuesta:
a) -48 - 42 = 12x + 6x --> -90=18x --> -5
b) 18 - 8x + 6x = 5x + 32 --> −7x=14 --> -2
c) 4x - 8x - 36 = -x - 3x - 36 --> 8x=72 --> x= 72/8 --> 9
Explicación paso a paso:
a) -8.6 - 3.14 = 12x + 6x
-48 -42 = 18x
-90 = 18x
-5 = x
b) 18 - 8x + 6x = 5x + 32
18 - 2x = 5x + 32
18 - 32 = 5x + 2x
-14 = 7x
-2 = x
c) 4x - 8x -4.9 = -x - 3x - 12.3
-4x - 36 = -4x - 36
