Question

Помогите решить пример :15 3/28-(4 11/28+y)=7-1 9/28 Пожалуйста помогитеееее прошууууууу!!!!!!!!!!!!

Answer 1

4 11/28+у=15 3/28-5 19/28
4 11/28+у=9 12/28
у=9 12/28-4 11/28
у=5 1/28

Answer 2

To solve the equation: 15 + 3/28 - (4 + 11/28 + y) = 7 - 1 + 9/28, we can follow these steps:

Step 1: Simplify both sides of the equation by combining like terms. On the left side, we have 15 + 3/28 - (4 + 11/28 + y). We can simplify this to: 15 + 3/28 - 4 - 11/28 - y.

On the right side, we have 7 - 1 + 9/28.

Step 2: Continue simplifying. On the left side, we can combine the whole numbers and fractions separately: 15 - 4 + 3/28 - 11/28 - y.

On the right side, we can combine the whole numbers and fractions separately: 7 - 1 + 9/28.

Step 3: Simplify further. On the left side, we have: 11 + (3/28 - 11/28) - y.

On the right side, we have: 6 + 9/28.

Step 4: Simplify the fractions. On the left side, we have: 11 + (-8/28) - y.

On the right side, we have: 6 + 9/28.

Step 5: Simplify further. On the left side, we have: 11 - 8/28 - y.

On the right side, we have: 6 + 9/28.

Step 6: Convert the fractions to a common denominator. On the left side, the denominator is already 28, so we don't need to make any changes.

On the right side, we need to convert the whole number 6 to a fraction with a denominator of 28: 6 = 6/1 = 168/28.

Step 7: Rewrite the equation with a common denominator. The equation becomes: 11 - 8/28 - y = 168/28 + 9/28.

Step 8: Combine the fractions. On the left side, we have: 11 - 8/28 - y.

On the right side, we have: (168 + 9)/28 = 177/28.

Step 9: Simplify the equation. 11 - 8/28 - y = 177/28.

Step 10: Solve for y. To solve for y, we need to isolate the variable on one side of the equation. Let's start by moving the constant term to the other side: 11 - 8/28 = 177/28 + y.

Next, we can simplify the left side: 11 - 8/28 = 11 - 1/4 = 44/4 - 1/4 = 43/4.

So the equation becomes: 43/4 = 177/28 + y.

To eliminate the fraction on the right side, we can multiply both sides of the equation by 28: 28 * (43/4) = 28 * (177/28 + y).

Simplifying further: 28 * (43/4) = 177 + 28y.

Step 11: Solve for y. To solve for y, we can isolate the variable by subtracting 177 from both sides of the equation: 28 * (43/4) - 177 = 28y.

Calculating the left side: 28 * (43/4) - 177 = 301 - 177 = 124.

So the equation becomes: 124 = 28y.

Finally, to solve for y, we divide both sides of the equation by 28: 124/28 = y.

Simplifying the left side: 124/28 = 31/7.

Therefore, the solution to the equation is: y = 31/7.
