Question

por favor preciso de cálculos

Answer 1

a) MMC  = 6

2x + 3x = 14 + 2x

5x - 2x = 14

3x = 14

x = 14/3

b) MMC = 6

2x - 4 +12x = 15x

15x -14 x = - 4

x = - 4

c) MMC = 6

2x - 10 + 9x - 3 = 24

11x = 24 + 13

11x = 37

x = 37/11

d) MMC = 15

3x - 3 = 15x - (10x - 5)

3x - 3 = 15x - 10x + 5
 
3x - 5x = 5 + 3

- 2x = 8

2x = - 8

x = - 8/2

x = - 4
