Ayuda Doy 30 Puntos Al Resolver Las Siguientes Ecuaciones☺♥ 3(3b + 1) = 3b - 15♥ 9y + 4 = 5(y - 4)♥ - 0, 4(0, 8z + 0, 1) - 0, 3 - 0, 6z = 0, 22♥ 7(14 - x) - 5x = - 16 + 2(x - 27)♥ 15m - 2(7 + 12m) = -?

3(3b + 1) = 3b - 15

9b + 3 = 3b - 15

9b - 3b = - 15 - 3

6b = - 18

b = - 18 / 6 = - 3

9y + 4 = 5(y - 4)

9y + 4 = 5y - 20

9y - 5y = - 20 - 4

4y = - 24

y = - 24 / 4 = - 6
