Explicación paso a paso:
1) (2x + 16)/3 = -2x
2x + 16 = 3(-2x)
2x + 16 = -6x
8x = -16
x = -2
2) 3 - 3x = 2x - 3
6 = 5x
6/5 = x
3) 12x - 18 = -4
4x - 9 = -2
x = 7/4
4) 1 = 6x/3
1 = 2x
1/2 = x
5) 3x + 2 = 3x + 2
0x = 0
x = R
Respuesta:
(2x/3)+(16/3) = - 4x/2
(2x/3)+(16/3) = -2x
2x/3+16/3 = -2x
2x/3+2x = -16/3
(2/3+2)x = -16/3
(8/3)x = -16/3
3(8/3)x = 3(-16/3)
8x = -16
8x/8 = -16/8
x = -2
5-2(1-x) = 2x-3
5-2+2x = 2x-3
3+2x = 2x-3
3+2x-2x = 2x-3+2x
3 = -3
Esta ecuación carece de solución
1+1/2(4x-6) = -2
1+(4x-6)/2 = -2 ; (4x-6) = 2(2x-3)
1+2(2x-3)/2 = -2
1+2x-3 = -2
-2+2x = -2
-2+2x+2 = -2+2
2x = 0
2x/2 = 0/2
x = 0
1-(x/3) = (5x/3)
1-(x/3)-1 = (5x/3)-1
-x/3 = (5x/3)-1
3(-x/3) = 3(5x/3)-1(3)
-x = 5x-3
-x+3 = 5x-3+3
-x+3 = 5x
-x+3+x = 5x+x
3 = 6x
3/3 = 6x/3
1 = 2x
1/2 = 2x/2
1/2 = x
x = 1/2
3+3x-1 = x+2+2x
2+3x = 3x+2
2+3x-2 = 3x+2-2
3x = 3x
3x-3x = 3x-3x
0 = 0
Esta ecuación posee infinitas soluciones
