es para el lunes pli 1. 5X+1 = 3X - 4 2. 5X - 9 = 3(x - 2) 3. 4X - 8 = -4(2x - 3) + 4 4. 3 - 4X = 2X + 5X - 19 5. -4 + X = 2 - 5X - 6

Respuesta:
1. x = -2,5
2. x = 1,5
3. x = 5/3
4. x = 2
5. x = 0
Explicación paso a paso:
1. 5X+1 = 3X - 4 = x = -2,5
2. 5X - 9 = 3(x - 2) = 2x = 3 x = 1,5
3. 4X - 8 = -4(2x - 3) + 4 = 12x = 20 x = 5/3
4. 3 - 4X = 2X + 5X - 19 = -11x = -22 x = 2
5. -4 + X = 2 - 5X - 6 = x = 0
RPTA:
1. x = -2,5
2. x = 1,5
3. x = 5/3
4. x = 2
5. x = 0
