Question

27:a=5+4 100-y=17+64 a•8=15+9

Answer 1

1) 27/а=5+4

9×а=27

а=27/9

а=3

2) 100-у=17+64

-у=81-100

-у=-19|×(-1)

у=19

3) а×8=15+9

а=24/8

а=3

Answer 2

27:а=5+4

27:а=9

9а=27

а=3

100-у=17+64

100-у=81

у=100-81

у=19

а*8=15+9

8*а=24

а=3

Answer 3

It appears that you have provided a series of equations. Let's break them down and solve for the variables:

1. 27: a = 5 + 4

   To solve for 'a,' simply add 5 and 4:

   a = 5 + 4 a = 9

2. 100 - y = 17 + 64

   To solve for 'y,' first add 17 and 64, and then subtract the result from 100:

   100 - y = 17 + 64 100 - y = 81

   Now, isolate 'y' by subtracting 81 from both sides:

   100 - y - 81 = 81 - 81 19 - y = 0

   Finally, solve for 'y' by adding 'y' to both sides:

   19 - y + y = 0 + y 19 = y

3. a * 8 = 15 + 9

   We already found that 'a' is 9 in the first equation. Now, we can use it to solve for a * 8:

   a * 8 = 9 * 8 a * 8 = 72

So, the solutions to your equations are: a = 9 y = 19 a * 8 = 72
