Question

Błagam obliczcie mi to: 100x + 20x - 20 + 2x = 13/24 * (200x+20x-20+x)
Błagam c:

Answer 1

122x-20=13\14(221x-20)
122x-20=2873\14x -260\14
122x-2873\14x = -260\14+20\1
1708\14x -2873\14x = -260\14+280\14
-1165\14x=20\14     /÷(-1165\14)
x=20\14÷(-1165\14)
x=20\14* (-14\1165)
x= - 4\233

Answer 2

100x + 20x - 20 + 2x = 13/24 * (200x + 20x - 20 + x)

122x - 20 = 13/24*(221x - 20)

122x - 13*221/24x = 20 - 13*5/6

122x - 119x - 17/24x = 20 - 10 - 5/6

2x + 7/24x = 9 + 1/6

55/24x = 55/6

55/4x = 55

1/4x = 1

X = 4
