Explicación paso a paso : 1.
9 + 2 = - 18 11 = - 18 11 + 18 = 292.
15 - 2u = 7 15 - 7 = 2u 8 = 2u 4 = u3.
6m - 8 = - 26 6m = - 26 + 8 6m = - 18 m = - 34.
- b - 20 = - 12 - 20 + 12 = b - 8 = b5.
- 3r - 9 = + 27 - 9 + 27 = 3r 18 = 3r 6 = r6.
23 - 4c = - 5 23 + 5 = 4c 28 = 4c 7 = c7.
- 4i = 13 = 7 - 4i = 13 - 7 - 4i = 6 6 = 4i 6 / 4 = i 3 / 2 = i.
. Espero que te sirva, salu2!
7x / 10 = 28 7x = 280 x = 40 (16x + 40 - 120) / 8 = x + 2 16x - 80 = 8x + 16 8x = 96 x = 12 (2x + 2 + 14x) / 14 = x - 2 2x + 2 + 14x = 14x - 2 2x + 2 = - 2 2x = - 4 x = - 2 (16x + 24 - 25x + 10) / 40 = (31x + 27) / 6…
