Answer 2

Let's solve the equation step by step.

Given equation: (2 3/10 - x) + 4/5 = 1 1/5

First, let's convert the mixed numbers to improper fractions for easier calculations:

2 3/10 can be written as (2 * 10 + 3) / 10 = 23/10

1 1/5 can be written as (1 * 5 + 1) / 5 = 6/5

The equation becomes:

(23/10 - x) + 4/5 = 6/5

Next, let's simplify the fractions:

23/10 - x + 4/5 = 6/5

To add the fractions, we need to have a common denominator. In this case, the common denominator is 10:

(23/10) - (x) + (4/5) = (6/5)

To get the common denominator of 10, we can multiply the numerator and denominator of the fractions:

(23/10) - (x) + (4/5) = (6/5)

(23/10) - (x) + (8/10) = (12/10)

Now we can combine the fractions:

(23/10) + (8/10) - (x) = (12/10)

31/10 - x = 12/10

Next, let's isolate the variable "x" by moving the constant terms to the other side of the equation:

31/10 - 12/10 = x

19/10 = x

So the solution to the equation is x = 19/10 or 1.9.

Therefore, X is equal to 1.9.
