Which related equation can be used to solve the equation?
m + 5 = - 7.3
A. m = - 7.3 - 5
B. m = 5 - 7.3
m = 7.3 - 5

m needs to be lone
move 5 to the other side of = sign dont forget to change sign
no when two signs are the same we add
so its like saying
m=-7.3 + (-5)
m=-12.3 now lets check it
-12.3 = + 5=-7.3
-12.3=-5 + (-7.3)
-12.3=-12.3 so we did it right
so your answer would be m=-7.3-5

It's A. m = - 7.3 - 5.
You can always check it ...
-7.3 - 5 = - 12.3
-12.3 + 5 = - 7.3
