Question

2•(4x–3)/3–4•(4x+5) –5•(x–4)/6=2

Me ajudem, por favor!​

Answer 1

Resposta:

(8x-6/3)-(16x+20/9)-(5x-20/6)

m.m.c=18

6(8x-6)- 2(16x+20)- 3(5x-20)=

48x-36 -32x -40 -15x+60=

48x -32x -15x= -60+40+36

x= +16

Answer 2

Resposta:

x = 52

Explicação passo a passo:

2.(4x-3)/3 - 4.(4x+5)/9 - 5(x-4)/6 = 2

Mmc (3,9,6)= 18

3,9,6: 2

3,9,3: 3

1,3,1: 3

1, 1, 1

= 2.3.3

= 18

[6.2.(4x-3) - 2.4.(4x+5) - 3.5.(x-4)]/18= [18.2]/18

12.(4x-3) - 8.(4x+5) - 15.(x-4) = 36

48x - 36 - 32x - 40 - 15x + 60 = 36

48x - 32x - 15x - 36 - 40 + 60 = 36

48x - 47x - 76 + 60 = 36

x - 16 = 36

x = 36+16

x = 52
