Answer 2

Respuesta:

1. x = 6
2. x = 3
3. x1 = 5/2 , x2 =5/12
4. x1 = 1 , x2 = -1
5. x1 = 3 , x2 = 9/20
6. x1 = 4/21 , x2 = 11/9

Explicación paso a paso:

Cómo no se comprenden si esas fracciones de los ejercicios 3, 4, 5 y 6 estén afectando a uno o a los dos componentes, te daré las dos resoluciones de ambos casos:

A) 9x = 54 -> x = 54/9 --> x = 6

B) 90/x = 30 -> 90/30 = x --> 3 = x

C1) (5x - 2)/3 = x + 1 --> 5x - 2 = 3x + 3 --> 5x - 3x = 3 + 2 --> 2x = 5 --> x = 5/2

C2) 5x - 2/3 = x + 1 -> 5x - x = 1 + 2/3 --> 4x = 5/3 --> x = 5/12

D1) 3x - 2 = (4x - 2)/2 -> 6x - 4 = 4x - 2 --> 6x - 4x = 4 - 2 --> 2x = 2 --> x = 1

D2) 3x - 2 = 4x - 2/2 -> 3x - 2 = 4x - 1 --> 1 - 2 = 4x - 3x --> -1 = x

E1) (2x - 1)/5 = (x + 1)/4 -> 4(2x - 1) = 5(x + 1) --> 8x - 4 = 5x + 5 --> 8x - 5x = 5 + 4 --> 3x = 9 --> x = 3

E2) 2x - 1/5 = x + 1/4 -> 2x - x = 1/4 + 1/5 --> x = 9/20

F1) (2 - 3x)/2 = (6x + 1)/3 -> 3(2 - 3x) = 2(6x + 1) --> 6 - 9x = 12x + 2 --> 6 - 2 = 12x + 9x --> 4 = 21x --> 4/21 = x

F2) 2 - 3x/2 = 6x + 1/3 -> (4 - 3x)/2 = (18x + 1)/6 --> 6(4 - 3x) = 2(18x + 1) --> 24 - 18x = 36x + 2 --> 24 - 2 = 36x - 18x --> 22 = 18x --> 22/18 = x --> 11/9 = x
