Which of the following equations are equivalent to -2m - 5m - 8 = 3 + (-7) + m? -15m = -4m -7m - 8 = m - 4 -3m - 8 = 4 - m m - 4 = -7m - 8 -8 - 7m = -4 + m -8 - 3m = 4 - m

To solve this problem, we must simplify the the equation:
Here is the base equation -2m - 5m - 8 = 3 + (-7) + m (Add all like terms):

#1 -2m - 5m - 8 = 3 + (-7) + m (Property of Addition)
#2 -7m - 8 = -4 + m (Most Simplified Equation)

The answer your would be the 2nd one. -7m - 8 = m - 4
