Answer 1

Ответ:

x=43/30 x=1 13/30 x=1,43

Answer 2

Let's break down the equation step by step:

1. Start with the expression on the left side: 2x + 11/15 ÷ 1/2

2. Simplify the division (division is the same as multiplying by the reciprocal): 11/15 ÷ 1/2 = (11/15) * (2/1) = (11/15) * 2 = 22/15

3. Now, we have the expression as: 2x + 22/15

4. Set this equal to 6 1/3. To do this, convert 6 1/3 to an improper fraction: 6 1/3 = 19/3

5. Now, we have the equation: 2x + 22/15 = 19/3

6. To isolate x, subtract 22/15 from both sides of the equation: 2x = 19/3 - 22/15

7. To subtract these fractions, you'll need a common denominator, which is 15: 2x = (19/3) - (22/15)

8. To find a common denominator, multiply 19/3 by 5/5 (which is equivalent to 1) to get a common denominator of 15: 2x = (19/3) * (5/5) - 22/15

9. Now, you can subtract the fractions: 2x = (95/15) - 22/15

10. Subtract the fractions: 2x = (95 - 22)/15 2x = 73/15

11. Finally, solve for x by dividing both sides by 2: x = (73/15) / 2

To simplify the final answer, you can also express it as a mixed number: x = (73/15) / 2 = 73/15 ÷ 2 = (73/15) * (1/2) = 73/30

So, the solution is: x = 73/30 or as a mixed number, x = 2 13/30
