Sagot :
-7m-8=m-4
Because if you combine like terms on both sides this will be the answer you get
Because if you combine like terms on both sides this will be the answer you get
-2m - 5m - 8 = 3 + (-7) + m= -1/2 (no need to give step by step figure this out)
the first one is correct, i will explain this one.
1) add 4 to both sides of the equation
m-4=-7m-8
m-4+4=-7m-8+4
2) simplify
add the numbers (a)
m=-7m-4
3) add 7m to both sides of the equation
m = -7m-4
m+7m=-7m-4+7m
4) simplify
a. combine like terms
8m = -4
5) divide both sides of the equation by the same term
8m = -4
8m/8=-4/8
6) simplify
cancel terms that are in both the numerator and denominator
divide the numbers
m=-1/2
