Question

respuesta a las ecuaciones

5(2x-1)+3(x-2)=10x5
2(x+3)-6(5+x)=3x+4
x-(2x+1)=8-(3x+3)​

Answer 1

Respuesta:

1. X = 61 / 13 o bien x= 4.692307

2. X = -4

3. X = 3

Explicación paso a paso:

1. 10x -5 +3x -6 =50

10x +3x -6 -5 = 50

13x -11 = 50

13x = 50 +11

13x = 61

x = 61 / 13

x = 4.692307

2. 2x +6 -30 -6x = 3x +4

2x - 6x -30 +6 = 3x +4

-4x -24 = 3x +4

-4x -3x = 4 +24

-7x =28

x = 28 / -7

x = -4

3. x - 2x -1 = 8 -3x -3

x -2x -1 = 8 -3 -3x

-x -1 = 5 -3x

-x +3x = 5 +1

2x = 6

x= 6 / 2

x = 3
