Question

15 3/28-(4 11/28+у)=7-1 9/28

Answer 1

15 3/28-4 11/28-у=7-1 9/28
10 20/28-у=5 19/28
у=10 20/28-5 19/28
у=5 1/28
15 3/28-(4 11/28+5 1/28)=5 19/28
15 3/28-9 12/28=5 19/28
5 19/28=5 19/28

Answer 2

To solve this equation, we'll first convert all mixed numbers to improper fractions:

15 3/28 = (15 * 28 + 3) / 28 = 423 / 28

4 11/28 = (4 * 28 + 11) / 28 = 123 / 28

1 9/28 = (1 * 28 + 9) / 28 = 37 / 28

So the equation becomes:

423 / 28 - (123 / 28 + у) = 37 / 28 - 1

Next, we'll simplify the expression inside the parentheses by combining like terms:

423 / 28 - (123 / 28 + у) = 37 / 28 - 1

423 / 28 - 123 / 28 - у = 9 / 28

300 / 28 - у = 9 / 28

Now, we'll isolate the variable у by adding у to both sides and then multiplying by -1:

300 / 28 - у = 9 / 28

300 / 28 - у + у = 9 / 28 + у

300 / 28 = 9 / 28 + у

291 / 28 = у

So the solution to the equation is:

у = 291 / 28, or approximately 10.39.
