Question

ECUACIONES DE PRIMER GRADO CON UNA INCOGNITA, RESOLVER LAS SIGUIENTES ECUACIONES CON SU RESPECTIVA COMPROBACION

1. 3 – 4X + 9 = 2X
2. 3X + 5 = 5X – 13
3. 10X – 10 = 5 ( X + 2 )
4. 6X + 1 = 2X + 5
5. 6X + 2 = 4X + 9
6. – 4X – 2X = – 9 – 3
7. 2X – 1 = 5X + 8
8. 3 + 3X – 1 = X + 2 + 2X
9. 2 ( 1 + 2X ) = 10
10. 2 ( 3X – 2 ) = 2
11. 2 ( 2X – 3 ) = 6 + X

Answer 1

Explicación paso a paso:

1. 3 – 4X + 9 = 2X

-4x-2x= -9-3

-6х = -12

x= -12/-6

x=2

2. 3X + 5 = 5X – 13

3x-5x= -13 -5

-2x= -18

x= -18/-2

x=9

3. 10X – 10 = 5 ( X + 2 )

10x -5x= 10+10

5x=20

x=20/5

x=4

4. 6X + 1 = 2X + 5

6x-2x=5-1

4x=4

x=4/4

x=1

5. 6X + 2 = 4X + 9

6x-4x=9-2

2x=7

x=7/2

6. – 4X – 2X = – 9 – 3

-6x= -12

x= -12/-6

x=2

7. 2X – 1 = 5X + 8

2x-5x=8+1

-3x=9

x=9/-3

x= -3

8. 3 + 3X – 1 = X + 2 + 2X

3x-3x =2-2

0=0

9. 2 ( 1 + 2X ) = 10

2+4x=10

4x=10-2

4x=12

x=12/4

x=3

10. 2 ( 3X – 2 ) = 2

6x-4=2

6x=2+4

6x=6

x=6/6

x=1

11. 2 ( 2X – 3 ) = 6 + X

4x-6=6+x

4x-x=6+6

3x=12

x=12/3

x=4

Espero que te sirva.....;)
