How do you solve #18-2m/5=-2#?

Answer 1

The solution to this equation is #m=50#

Whenever I see an equation with a fraction, I like to get rid of it. You can do that in this case by multiplying by #5# (don't forget to do it at the right side): #5*18-\cancel(5) * 2/\cancel(5) m=5*(-2)# #90-2m=-10# Now we can bring the 90 over to seperate the #m#: #\cancel(90-90)-2m=-10-90# #-2m=-100# Now, all we need to do is divide by #-2# #\cancel(-2)m/\cancel(-2)=-100/-2# #m=50#

To solve the equation (18 - \frac{2m}{5} = -2):

Multiply both sides of the equation by 5 to eliminate the fraction.
Simplify the equation.
Subtract 18 from both sides.
Divide both sides by -2.

The solution is (m = 25).

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
