Answer 1

100-y=17+64;

100-y=81;

y=100-81;

y=19

Answer 2

-у=17+64-100
-у=-19
У=19

Answer 3

To solve the equation 100 - y = 17 + 64, you need to isolate the variable y on one side of the equation. Here's how you can do it step-by-step:

1. Combine the constants on the right side of the equation: 17 + 64 = 81
2. Now, the equation becomes: 100 - y = 81
3. To isolate y, you need to get rid of the constant term (-y) on the left side. To do this, you can perform the inverse operation, which is adding y to both sides of the equation: 100 - y + y = 81 + y 100 = 81 + y
4. Next, isolate y by subtracting 81 from both sides of the equation: 100 - 81 = 81 + y - 81 19 = y

The solution to the equation is y = 19.
