Question

realice las siguientes ecuaciones 6+2x-4=x-1, 1-3x=2x-9, 7x=3x+8, 5x-1=-x+5+4

Answer 1

Respuesta:

• x = -7
• x = 2
• x = 2
• x = 5/3 --> x = 1.6..

Explicación paso a paso:

6+2x-4=x-1

2x - x = -1 -6

x = -7

1-3x=2x-9

1 +9 = 2x +3x

10 = 5x

10/5 = x

2 = x

7x=3x+8

7x -3x = 8

4x = 8

x = 8/4

x = 2

5x-1=-x+5+4

5x +x = +5 +4 +1

6x = 10

x = 10/6

x = 5/3

x = 1.6...
