Answer 2

Respuesta:

Explicación paso a paso:

2x – 4 = 5 – x

2x+x=5+4

3x=9

x=9/3

x=3

4(x + 5) = 3-2x/2

4x+20=3-2x/2

8x+40=3-2x

8x+2x=3-40

10x=-37

x=-37/10    x= -3,7

8-3n/3=6-5n/6

48-18n=18-15n

-18n+15n=18-48

-3n=-30

n=-30/-3

n=10

x+2/3+x-4/6=1

2(x+2)+x-4=6

2x+4+x-4=6

3x=6

x=6/3

x=2
