Resuelva :8 X + 5 = 456 X - 9 = 544 X + 9 = 723 X - 8 = 287 X + 6 = 60?

Resuelva : 8 X + 5 = 45 6 X - 9 = 54 4 X + 9 = 72 3 X - 8 = 28 7 X + 6 = 60.

En resumen

8 X + 5 = 45 8X = 45 - 5 8X = 40 X = 40 / 8 X = 5 6 X - 9 = 54 6X = 54 + 9 6X = 63 X = 63 / 6 simplificando X = 21 / 2 4 X + 9 = 72 4X = 72 - 9 4X = 63 X = 63 / 4 3 X - 8 = 28 3X = 28 + 8 3X = 36 X = 36 / 3 X = 12 7 X + 6 = 60 7X = 60 - 6 7X = 54 X = 54 / 7.

8 X + 5 = 45

8X = 45 - 5

8X = 40

X = 40 / 8

X = 5

6 X - 9 = 54

6X = 54 + 9

6X = 63

X = 63 / 6 simplificando

X = 21 / 2

4 X + 9 = 72

4X = 72 - 9

4X = 63

X = 63 / 4

3 X - 8 = 28

3X = 28 + 8

3X = 36

X = 36 / 3

X = 12

7 X + 6 = 60

7X = 60 - 6

7X = 54

X = 54 / 7.
