4. × - 56 = 815?

4. × - 56 = 8 15. 3 + 19. × = 9. 10 - 7 5× + 36 : 6 = 22 + 2. 7 5. × - 14 - 2. × = 7. 4.

En resumen

4x - 56 = 8 4x = 8 + 56 4x = 64 x = 64 : 4 x = 16 45 + 19x = 90 - 7 19x = 90 - 7 - 45 19x = 38 x = 38 : 19 x = 2 5x + 6 = 22 + 14 5x = 36 - 6 5x = 30 x = 30 : 5 x = 6 5x - 2x = 28 + 14 3x = 42 x = 42 : 3 x = 14.

4x - 56 = 8

4x = 8 + 56

4x = 64

x = 64 : 4

x = 16

45 + 19x = 90 - 7

19x = 90 - 7 - 45

19x = 38

x = 38 : 19

x = 2

5x + 6 = 22 + 14

5x = 36 - 6

5x = 30

x = 30 : 5

x = 6

5x - 2x = 28 + 14

3x = 42

x = 42 : 3

x = 14.
