Answer:
m = -100
Step-by-step explanation:
So in order to solve this equation we are going to have to convert 1/5m to a decimal, this will make it easier to solve the equation:
1/5m = 0.2m
Next we are going to take our 0.2m and place it within the equation where 1/5m is:
⅕m - 12 = -32 or 0.2m - 12 = -32
So now we are going to add 12 to both sides of the equal sign in the equation to segregate the 0.2m within the equation:
0.2m - 12 = -32 or 0.2m + (-12 + 12) = (-32 + 12)
making the equation look like this:
0.2m = -20
now we are going to divide 0.2 from both 0.2m and -20 to get the value of m:
0.2m/0.2 = -20/0.2
Thus getting the answer:
m = -100
So how do we know that -100 is the value of m? well we check our work of course by substituting -100 in place of m!
⅕(-100) - 12 = -32 or 0.2(-100) - 12 = 32
0.2(-100) - 12 = 32
-20 - 12 = -32
-32 = -32
