Answer:
M= -10/4
M = -5/2
-5/4 + m = -15/4
Explanation:
3/4 + m = -7/4
Subtract 3/4 from both sides
3/4 + m - 3/4 = -7/4 - 3/4
m = (-7-3) / 4
m = -10/4
m = -5/2
Check the options
11/4 + m = -1/4
m = -1/4 - 11/4
m = (-1-11) /4
m = -12/4
m = -3
-5/4 + m = -15/4
m = -15/4 + 5/4
m = (-15+5) /4
m = -10/4
m = -5/2
