7w + 1 = 15 1 - (x + 2) = 10 9 = - 3(w - 4) 7m - 7 + 2 + 6m?

7w + 1 = 15 1 - (x + 2) = 10 9 = - 3(w - 4) 7m - 7 + 2 + 6m.

En resumen

7w + 1 = 15 7w = 15 - 1 7w = 14 w = 14 / 7 w = 2 9 = - 3(w - 4) 9 = - 3w + 12 3w = 12 - 9 3w = 3 w = 3 / 3 w = 1 7m - 7 + 2 = 2 + 6m 7m - 6m = 2 + 7 - 2 m = 7.

7w + 1 = 15

7w = 15 - 1

7w = 14

w = 14 / 7

w = 2

9 = - 3(w - 4)

9 = - 3w + 12

3w = 12 - 9

3w = 3

w = 3 / 3

w = 1

7m - 7 + 2 = 2 + 6m

7m - 6m = 2 + 7 - 2

m = 7.
