20 points! you can choose more than one answer (i already know the second one is right but i need one more that is equivalent) which of the following equations are equivalent to -2m - 5m - 8 = 3 + (-7) + m? 1) -15m = -4m 2) -7m - 8 = m - 4 3) -3m - 8 = 4 - m 4) m - 4 = -7m - 8 5) -8 - 7m = -4 + m 6) -8 - 3m = 4 - m
