using the digits one through nine, at most on time each, fill in the blanks to make an equation where the solution is x = 77.7. explain how you are correct
x—_ _ . _ = _ _ . _
WTF kind of math is that?
9*8 + 5.7 = 77.7
WTF oobleck is right it equals to 79

To solve this equation and make the solution x = 77.7 using the digits 1 through 9 at most one time each, we can follow these steps:
Step 1: Let's start by analyzing the given equation:
x—_ _ . _ = _ _ . _
The decimal point separates the whole number part from the decimal part of the equation. Since the solution requires x = 77.7, we know that 77 is the whole number part, and we need to fill in the blanks to find the decimal part.
Step 2: The decimal part has two digits and one decimal point, represented by the blanks. Since we can use each digit from 1 to 9 at most one time and the decimal point is already present, we need to find two unique digits to fill the blanks.
Step 3: To find those two unique digits, we need to consider the remaining digits from 1 to 9 after using the digit 7 for the whole number part. We can choose any two digits that are not 7 from the remaining set of digits.
For example, we can choose:
First blank: 3
Second blank: 9
Step 4: Let's fill in the blanks in the original equation with the chosen digits:
x—_ _ . _ = 77.3
Step 5: Evaluate the equation to verify the solution:
77.3 = 77.7
Since the equation is true, the solution x = 77.7 is correct. By filling the blanks with the unique digits 3 and 9, we achieved the desired solution.
9 x 8 . 7 = 77.7
This equation is correct because 9 x 8 = 72 and 72 + 7 = 77.7. Therefore, the equation 9 x 8 . 7 = 77.7 is correct and the solution is x = 77.7.
