Answer 1

Ответ:

Объяснение:

8у-56-6у-27=15

8у-6у=15+56+27

2у=98

у=98/2

у=49

Ответ: 49

Answer 2

Ответ:

$49$

Объяснение:

$8(y-7)-3(2y+9)=15;$

$8y-56-6y-27=15;$

$2y-83=15;$

$2y=83+15;$

$2y=98;$

$y=49;$

Answer 3

To solve the equation 8(y - 7) - 3(2y + 9) = 15, you can follow these steps:

1. Distribute the constants outside the parentheses to the terms inside the parentheses:

   8 * y - 8 * 7 - 3 * 2y - 3 * 9 = 15

2. Simplify each term:

   8y - 56 - 6y - 27 = 15

3. Combine like terms by adding or subtracting them:

   (8y - 6y) + (-56 - 27) = 15

   2y - 83 = 15

4. Add 83 to both sides of the equation to isolate the variable term:

   2y - 83 + 83 = 15 + 83

   2y = 98

5. Finally, divide both sides by 2 to solve for y:

   2y/2 = 98/2

   y = 49

So, the solution to the equation 8(y - 7) - 3(2y + 9) = 15 is y = 49.
