Answer 2

Ответ:

А) $12$$\frac{2}{7}$-х=$2\frac{1}{6}$

-х=$\frac{13}{6}-\frac{86}{7}$

-х=$-\frac{425}{42}$

х=$10\frac{5}{42}$

Б) $3\frac{5}{24} +x=5\frac{9}{16}$

$\frac{77}{24}+x=\frac{89}{16}$

x=$\frac{113}{48}$

x=$2\frac{17}{48}$

Answer 3

Problem A: 12 + 2/7 - x = 2 + 1/6

To solve this equation, we need to isolate the variable x. Let's go step by step:

1. Combine the whole numbers and fractions on both sides of the equation separately: - On the left side: 12 + 2/7 = 86/7 - On the right side: 2 + 1/6 = 13/6

2. Rewrite the equation with the combined fractions: - 86/7 - x = 13/6

3. To get rid of the fractions, we can find a common denominator for both sides of the equation. The least common multiple (LCM) of 7 and 6 is 42.

4. Multiply both sides of the equation by 42 to eliminate the fractions: - (86/7) * 42 - x * 42 = (13/6) * 42

5. Simplify the equation: - 86 * 6 - 42x = 13 * 7

6. Solve for x: - 516 - 42x = 91 - Subtract 516 from both sides: - -42x = -425 - Divide both sides by -42: - x = 425/42

Therefore, the solution to the equation 12 + 2/7 - x = 2 + 1/6 is x = 425/42.
