1• 5x + 30 = 1002• 4x - 12 = 36?

1• 5x + 30 = 100 2• 4x - 12 = 36.

En resumen

5x + 30 = 100 5x = 100 - 30 5x = 70 x = 70 / 5 x = 14 4x - 12 = 36 4x = 36 + 12 4x = 48 x = 48 / 4 x = 12.

5x + 30 = 100

5x = 100 - 30

5x = 70

x = 70 / 5

x = 14

4x - 12 = 36

4x = 36 + 12

4x = 48

x = 48 / 4

x = 12.
