Answer 2

Let's solve the equations one by one:

Equation 1: 27 + а = 5 + 4

To solve for 'а', we need to isolate it on one side of the equation. First, simplify the equation:

27 + а = 9

Next, subtract 27 from both sides to isolate 'а':

а = 9 - 27

а = -18

Therefore, 'а' is equal to -18.

Equation 2: 100 - у = 17 + 64

To solve for 'у', we need to isolate it on one side of the equation. First, simplify the equation:

100 - у = 81

Next, subtract 100 from both sides to isolate 'у':

-у = 81 - 100

-у = -19

Finally, multiply both sides by -1 to solve for 'у' (this will change the sign):

у = -19 * -1

у = 19

Therefore, 'у' is equal to 19.

Equation 3: а • 8 = 15 + 9

To solve for 'а', we need to isolate it on one side of the equation. First, simplify the equation:

8а = 24

Next, divide both sides by 8 to solve for 'а':

а = 24 / 8

а = 3

Therefore, 'а' is equal to 3.
