Question

me ayudan con las ecuaciones xfa?​

Answer 1

Respuesta:

1. 6x -2x = 20

6x -2x = 20

4x = 20

x = 20/4

x = 5

2. 4x +5x =81

4x +5x = 81

9x = 81

x = 81/9

x= 9

3. 7a +5a = 48

7a +5a = 48

12a = 48

a = 48/12

a =4

4. 12x -7x = -30

12x -7x = -30

5x = -30

x = 30/5

x=6

5. 3x -6x = -24

3x -6x = -24

-3x = -24

x = -24/-3

x = +8

6. 8x -2x = -15 -3

8x -2 = -15 -3

8x = -15 -3 +2

8x = -20

x = 10/8

x = 1.25

7. 10m -13m = 20 -29

10m -13m = 20 -29

3m = -9

m = 9/3

m = 3

8. 9 +2x -1 = 6x

+2x -6x = -9 +1

-6x = -8

x= 6/8

x = 0.75

9. 14 -3x +2 = 5x

14 -3x +2 = 5x

-3x -5x = -14 -2

-8x = +16

x = 16/8

x = 2

10. 6x +5 = x +40

6x +5 = x +40

6x x = +40 -5

7x = +35

x = 35/7

x = 5

11. 7x -3 = 3x +13

7x -3 = 3x +13

7x -3x = +13 +3

4x = +16

x = 16/4

x= 4

mmm espero que te ayude y que se entienda y que este bien xd
