To solve for x, we first need to simplify the inequality:

1,75 + 2x/3 ≤ x + 1 2/3

First, convert 1 2/3 to a mixed number:

1 2/3 = 5/3

Then, we can simplify the inequality further:

1.75 + 2x/3 ≤ x + 5/3

Next, we can subtract x from both sides:

1.75 + x/3 ≤ 5/3

Next, we can subtract 1.75 from both sides:

x/3 ≤ 5/3 - 1.75

x/3 ≤ 5/3 - 5/4

x/3 ≤ 3/12

x/3 ≤ 1/4

Now, we can multiply both sides by 3 to solve for x:

x ≤ 3/4

Therefore, the solution to the inequality is x ≤ 3/4.
