A system of equations is shown below. { 4 x + y = 8/ 2 x − 3 y = 18} If the first equation is multiplied by a constant and the result is added to the second equation, which equation could result?

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
