Question

12x - 8 + 10 = 6x - 11 ; 13x - 8x + 20 = 3x - 15 + 4

Answer 1

Respuesta:

a) x = -13/6

b) x = -31/2

Explicación paso a paso:

a) 12x - 8 + 10 = 6x - 11

12x - 6x = -11 +8 -10

6x = -21 +8

6x = -13

x = -13/6

x = -2.16...

b) 13x - 8x + 20 = 3x - 15 + 4

13x - 3x -8x = -15 + 4 -20

2x = - 31

 x = -31/2

 x = -15.5

Answer 2

Respuesta:

12x - 8 + 10 = 6x - 11

12x+2=6x-11

12x=6x-13

6x= -13

x= - 13/6

13x - 8x + 20 = 3x - 15 + 4

5x+20=3x-15+4

5x+20=3x-11

5x=3x-31

2x= -31

x= - 31/2
