Resuelve las siguientes ecuaciones

1. 4x - 1 = 2x + 4
2. -3(x - 2) = 11
3. 5y + 2 = 3y -14
4. -7x + 5 = -8x + 14
5. 5(2x + 1) = 4 (3x -8)
6. -6(x - 4) + 2 = 42

Answer 1

1. 4x - 1 = 2x + 4
4x-2x =4 +1
2x = 5
X=5/2

2. -3(x - 2) = 11 distributiva
-3x+6 = 11
-3x= 11-6
X= 5/-3
X= -(5/3)

3. 5y + 2 = 3y -14
5y-3y = -14 -2
2y = -16
Y= -16/2
Y= -8

4. -7x + 5 = -8x + 14
-7x +8x= 14 -5
X= 9

5. 5(2x + 1) = 4 (3x -8) distributiva
10x +5 = 15x -32
5+32 = 15x -10x
37 = 5x
37/5 = x
6. -6(x - 4) + 2 = 42 distributiva
-6x + 24 +2= 42
-6x +28 = 42
-6x = 42 -28
X = 14 / (-6)
X= 7/3
