Question

Помогите пожалуйста (2/15 + y) - 7/30 = 1/10•

Answer 1

Ответ:

y=0,2

Пошаговое объяснение:

(2/15 + y) - 7/30 = 1/10

2/15+y-7/30=1/10

y=1/10-2/15+7/30

y=1/5 (или 0,2)

Answer 2

To solve the equation (2/15 + y) - 7/30 = 1/10, we can follow these steps:

1. Find a common denominator for the fractions involved. In this case, the common denominator is 30, since it is divisible by both 15 and 30.

2. Rewrite the fractions with the common denominator: - (2/15) becomes (4/30) - (7/30) remains the same - (1/10) remains the same

3. Substitute the rewritten fractions into the equation: (4/30 + y) - (7/30) = 1/10

4. Combine like terms on the left side of the equation: (4/30 - 7/30) + y = 1/10

5. Simplify the expression on the left side: -3/30 + y = 1/10

6. Simplify further by dividing both sides of the equation by the coefficient of y, which is 1: (-3/30) + y/1 = (1/10) / 1

7. Simplify the fractions: -1/10 + y = 1/10

8. To isolate y, we can add 1/10 to both sides of the equation: -1/10 + y + 1/10 = 1/10 + 1/10

9. Simplify the expression on the left side: y = 2/10

10. Simplify the fraction: y = 1/5

Therefore, the solution to the equation (2/15 + y) - 7/30 = 1/10 is y = 1/5.
