Question

ayuda:
2x - 5 = 19
x = 12
x = 11
x =13

6x + 5 = 4x + 17
x = 7
x = 8
x = 6

2x/3 = 4

x = 6
x = -6
x= -7

2x +4 = x + 9

x= 5
x = 4
x =7

2x + 16 = 3x + 9

x = 8
x = 9
x = 7

2x -1 = 4x + 5

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

x/2 +16 = 34

x = 36
x = 38
x = 39

3x/2 -1 = 2

x = 1
x = 2
x = 5

2x - 5 +x + 3 + x + 9 = 75

x = 17
x = 18
x = 20

Answer 1

Respuesta:

Explicación paso a paso:

2x-5=19

2x=19+5

2x=24

x=24/2

x=12

6x+5=4x+17

6x-4x=17-5

2x=12

x=12/2

x=6

2x/3=4

2x=(4)(3)

2x=12

x=12/2

x=6

2x+4=x+9

2x-x=9-4

x=5

2x+16=3x+9

2x-3x=9-16

-x=-7

x=-(-7)

x=7

2x-1=4x+5

2x-4x=5+1

-2x=6

x=6/-2

x=-3

x/2 +16=34

x/2=34-16

x/2=18

x=(18)(2)

x=36

3x/2 -1=2

3x/2=2+1

3x/2=3

3x=(3)(2)

3x=6

x=6/3

x=2

2x-5+x+3+x+9=75

4x=75-7

4x=68

x=68/4

x=17
