Respuesta:
a) X = -3 b) X = 7/4
Explicación paso a paso:
a) 1 + 4X - 8 = 3X + 5X + 5
1 + 4X - 8 = 8X + 5
1 + 4X = 8X + 5 + 8
1 = 8X + 5 + 8 - 4X
1 = 8X + 13 - 4X
1 = 4X + 13
1 - 13 = 4X
- 12 = 4X
-12/4 = X
- 3 = X
b) X + 3(X - 1) = 6 - 4(2x + 3)
X + 3X - 3 = 6 - 8X + 12
4X - 3 = 18 - 8X
4X - 3 + 8X = 18
12X - 3 = 18
12X = 18 + 3
12X = 21
X = 21/12
X = 7/4
