Explicación paso a paso:
1. a) 3x + 6 + 1 =-5
3x = -5 - 7
3x = - 12
x = -4
b) 4x + 4 - 2x - 6 = x
2x - 2 = x
x = 2
c) 2x + 6 - 3 = 3x + 3 - 1
2x + 3 = 3x + 2
1 = x
x = 1
1-
a) 4m + 8 - 2m + 2 = - 2
2m + 10 = -2
2m = - 12
m = -6
b) 3y + 9 - 4y + 4 = 3y + 3 + 2
-y + 13 = 3y + 5
8 =4y
y = 2
c) 3a + 6 + 5a - 5 = 2 - 3a - 3
8a + 1 = -1 - 3a
11 a = - 2
a = -2/11
1-. a) 2 + 3x - 3 + 6x + 12 = 5 -2x - 6 + 1
11 + 9x = - 2 x
11x = - 1 1
x = - 1
b) 12x + 6 - 12x - 3 + x = 2
3 + x = 2
c) 3 - 8x - 4 - 6 + 9x + 2 = 0
-7 + x = 0
x = 7
