Question

(99-9y) - 8 + 14=86​

Answer 1

Пошаговое объяснение:

$(99 - 9y) - 8 + 14 = 86 \\ 99 -9y= 86 + 8 - 14 \\ 99 - 9y = 80 \\ - 9y = 80 - 99 \\ - 9y = - 19 \\ y = 2 \frac{1}{9}$

Answer 2

( 99 - 9у ) - 8 + 14 = 86

( 99 - 9у ) - 8 = 86 - 14

99 - 9у = 72 + 8

99 - 9у = 80

9у = 99 - 80

у = 19 ÷ 9

у = 19/9

у = 2 1/9

Answer 3

To solve the equation (99-9y) - 8 + 14 = 86, follow these steps:

1. First, simplify the equation by combining like terms on the left side:

   (99 - 9y) - 8 + 14 = 86 99 - 9y - 8 + 14 = 86

2. Combine the constants on the left side:

   (99 - 8 + 14) - 9y = 86 (105) - 9y = 86

3. Now, isolate the variable "y" by moving the constants to the right side:

   105 - 9y = 86

4. To isolate "-9y," subtract 105 from both sides of the equation:

   -9y = 86 - 105

5. Perform the subtraction on the right side:

   -9y = -19

6. Finally, divide both sides by -9 to solve for "y":

   y = -19 / -9 y = 19/9

So, the solution to the equation is:

y = 19/9 or approximately y = 2.1111 (rounded to four decimal places).
