Answer 2

To solve the equation 11 2/5 - 3 1/5 - x = 2 4/5, we need to simplify the expressions on both sides and isolate the variable x.

Let's start by converting the mixed numbers into improper fractions:

11 2/5 = (5 * 11 + 2) / 5 = 57/5 3 1/5 = (5 * 3 + 1) / 5 = 16/5 2 4/5 = (5 * 2 + 4) / 5 = 14/5

Now we can rewrite the equation as:

57/5 - 16/5 - x = 14/5

To combine the fractions on the left side, we need a common denominator, which in this case is 5:

(57 - 16) / 5 - x = 14/5

41/5 - x = 14/5

To isolate the variable x, we can subtract 41/5 from both sides:

41/5 - 41/5 - x = 14/5 - 41/5

• x = -27/5

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

x = 27/5

So the solution to the equation is x = 27/5 or x = 5 2/5.
