3x +4 = 7x + 6

1/5x + 11= 2/3x + 1/2

7/6x - 1/8x -8 = 3/5x + 6

HALLAR EL VALOR DE X ayuda plisss

Answer 1

a) 3x +4 = 7x +6

3x -7x = 6 - 4

-4x = 2

x = - 2/4

x= - 1/2

x= -0,5

b) 1/5x +11 = 2/3x + 1/2

1/5x - 2/3x = 1/2 - 11

- 7/15x = - 21/2

x = -21/2 / 7/15

x= - 45/2

x= -22,5

c) 7/6x - 1/8x -8 = 3/5x + 6

7/6x - 1/8x - 3/5x = 6 +8

53/120x = 14

x = 14 / 53/120

x= 1680/53

x= 31,69
