me ajudem glr pvf
*equação fácil*​

Answer 1

Resposta:

x=12

Explicação passo-a-passo:

(2x-4)/5-37/6=(20-x)/4-[(2x+1)/2]/3

(2x-4)/5-37/6=(20-x)/4-(2x+1)/6

mmc=60

12(2x-4)-10.37=15(20-x)-10(2x+1)

24x-48-370=300-15x-20x-10

24x-418=290-35x

24x+35x=290+418

59x=708

x=708/59

x=12

Answer 2

Resposta:

Essa é fácil em...

2x-4 1 20 - x x + 1/2

------- - 6 ---- = --------- - ---------

5 6 4 3

2x - 4 37 20 - x 2x/2+1/2

-------- - ------ = --------- - --------------

5 6 4 3

mmc de 5,6,4 e 3

5,6,4,3/2

5,3,2,3/2

5,3,1,3/3

5,1,1,1/5

1,1,1,1

2² x 3 x 5 = 60

12(2x-4) - 10(37) 15(20-x) - 20(2x+1/2)

------------------- = -------------------------

60 60

24x - 48 - 370 300 - 15x - 40x/2- 20/2

---------------- = ---------------------------

60 60

24x - 418 300 - 15x - 20x - 10

----------- = -------------------------

60 60

24x - 418 290 - 35x

----------- = ----------------

60 60

24x - 418 = 290 - 35x

24x + 35x = 290 + 418

59x = 708

x = 708/59

x = 12
