Answer 3

To solve the equation 12.89 + (-x) = -24/5, we can start by isolating the variable x on one side of the equation.

First, we can simplify the right-hand side by converting the mixed number -24/5 to an improper fraction:

-24/5 = -4 4/5 = -(4 + 4/5) = -4 - 4/5 = -4.8

Now we have the equation:

12.89 + (-x) = -4.8

Next, we can simplify the left-hand side by adding 12.89 and -x:

12.89 + (-x) = -4.8 12.89 - 12.89 + (-x) = -4.8 - 12.89 -x = -17.69

Finally, we can solve for x by multiplying both sides by -1:

-x = -17.69 (-1)(-x) = (-1)(-17.69) x = 17.69

Therefore, the solution to the equation 12.89 + (-x) = -24/5 is x = 17.69.
