Question

100-y=17+64 какой ответ уравнения

Answer 1

$100 - y = 17 + 64 \\ - y = 17 + 64 - 100 \\ - y = - 19 \\ y = 19$
Ответ: у = 19

Answer 2

100-y=17+64

100-y=81

-y=81-100

-y=-19

y= -19:(-1)

y=19

Answer 3

To solve the equation, we need to isolate the variable "y" on one side of the equation. Let's go step by step:

1. Subtract 17 from both sides of the equation: 100 - y - 17 = 17 + 64 - 17

2. Simplify both sides: 83 - y = 64

3. Now, we need to isolate the variable "y" on one side of the equation. To do that, we will subtract 83 from both sides of the equation: 83 - y - 83 = 64 - 83

4. Simplify both sides: -y = -19

5. Finally, to solve for "y," we need to multiply both sides by -1 (to get y by itself): (-1) * (-y) = (-1) * (-19) y = 19

So the solution to the equation is: y = 19.
