Question

72/80-(x - 12/80) = 15/80

Answer 1

Ответ:

Пошаговое объяснение:

72/80-(x - 12/80) = 15/80

72/80 - x + 12/80 = 15/80

60/80 - x = 15/80

x = 60/80 - 15/80

x = 45/80

x = 9/16

Answer 3

To solve the equation 72/80 - (x - 12/80) = 15/80, we'll follow these steps:

1. Simplify the expression inside the parentheses on the left side: x - 12/80 = (80x - 12)/80.
2. Substitute the simplified expression back into the equation: 72/80 - (80x - 12)/80 = 15/80.
3. Simplify the fractions by finding a common denominator, which is 80 in this case.
4. Solve the equation step by step to isolate x.

Let's work through these steps:

Step 1: The equation becomes: 72/80 - (80x - 12)/80 = 15/80.

Step 2: Combining the fractions, we have: (72 - 80x + 12)/80 = 15/80.

Step 3: The fractions have a common denominator of 80, so we can proceed with the equation: (72 - 80x + 12)/80 = 15/80.

Step 4: Now, we'll solve for x by cross-multiplying and isolating the variable:

(72 - 80x + 12) = 15 Simplifying further: 72 - 80x + 12 = 15 84 - 80x = 15 -80x = 15 - 84 -80x = -69

Divide both sides by -80: x = (-69)/(-80)

Simplifying the fraction: x = 69/80

Therefore, the solution to the equation 72/80 - (x - 12/80) = 15/80 is x = 69/80.
