Question

131/30-(49/20-х)=49/60​

Answer 1

Ответ:

Пошаговое объяснение:

49/20 - х = 131/30 - 49/60

147/60 - х = 262/60 - 49/60

147/60 - х = 213/60

х = 147/60 - 213/60

х = -66/60

х = -11/10

х = -1. 1/10

Answer 2

To solve for the value of x in the equation:

$\frac{131}{30} - \left(\frac{49}{20} - x\right) = \frac{49}{60}$

You can follow these steps:

Step 1: Simplify the expressions inside the parentheses:

$\frac{131}{30} - \frac{49}{20} + x = \frac{49}{60}$

Step 2: Find a common denominator for the fractions on the left side of the equation. In this case, the common denominator is 60:

$\frac{131 \cdot 2}{30 \cdot 2} - \frac{49 \cdot 3}{20 \cdot 3} + x = \frac{49}{60}$

Step 3: Simplify the fractions with the common denominator of 60:

$\frac{262}{60} - \frac{147}{60} + x = \frac{49}{60}$

Step 4: Combine the fractions on the left side:

$\frac{262 - 147}{60} + x = \frac{49}{60}$

Step 5: Subtract the fraction on the left side from both sides of the equation:

$x = \frac{49}{60} - \frac{115}{60}$

Step 6: Subtract the fractions:

$x = \frac{49 - 115}{60}$

Step 7: Simplify the right side:

$x = \frac{-66}{60}$

Step 8: Simplify the fraction by dividing both the numerator and denominator by their greatest common divisor, which is 6:

$x = \frac{-11}{10}$

So, the solution to the equation is $x = -\frac{11}{10}$.
