Question

(3 11/15 + у) - 5 7 /15 =3 4/15

Answer 1

(3 11/15 + y) - 5 7/15 = 3 4/15

(56/15 + y) - 5 7/15 = 3 4/15

(56/15 + y) - 82/15 = 3 4/15

(56/15 + y) - 82/15 = 49/15

56/15 + y - 82/15 = 49/15

- 26 + y = 49/15

y = 49/15 + 26/15

y = 75/15

y = 5

Ответ: y = 5

Answer 2

To solve the equation (3 11/15 + у) - 5 7/15 = 3 4/15, you can follow these steps:

Step 1: Convert mixed numbers to improper fractions. 3 11/15 as an improper fraction is (3 * 15 + 11)/15 = 46/15. 5 7/15 as an improper fraction is (5 * 15 + 7)/15 = 82/15. 3 4/15 as an improper fraction is (3 * 15 + 4)/15 = 49/15.

Now, your equation becomes:

(46/15 + у) - (82/15) = 49/15

Step 2: Simplify the equation by subtracting (82/15) from both sides:

(46/15 + у) - (82/15) - (82/15) = 49/15 - (82/15)

(46/15 + у) - (164/15) = -33/15

Step 3: Add (164/15) to both sides to isolate у:

(46/15 + у) - (164/15) + (164/15) = -33/15 + (164/15)

46/15 + у = 131/15

Step 4: Now, subtract 46/15 from both sides to solve for у:

(46/15 + у) - (46/15) = (131/15) - (46/15)

у = 85/15

Step 5: Simplify the fraction:

у = 17/3

So, the solution to the equation is у = 17/3.
