Question

27:a=5+4 100-y=17+64

Answer 1

27÷а=5+4 100-у=17+64

27÷а=9 100-у=81

а=27÷9 у=100-81

а=3 у=19

27÷3=5+4 100-19=17+64

9=9 81=81

Answer 2

27:а= 5+4
27 : а = 9
а = 27:9
а = 3

100- у= 17+64
100 - у = 81
у = 100 - 81
у = 9

Answer 3

To solve the given equations, let's go step by step:

Equation 1: 27 + a = 5 + 4

To solve for 'a,' we need to isolate the variable on one side of the equation. Let's simplify the equation:

27 + a = 9

Subtracting 27 from both sides:

a = 9 - 27

a = -18

So, the value of 'a' is -18.

Equation 2: 100 - y = 17 + 64

To solve for 'y,' we'll follow a similar process. Let's simplify the equation:

100 - y = 81

Subtracting 100 from both sides:

-y = 81 - 100

-y = -19

To isolate 'y,' we need to multiply both sides by -1 (to change the sign):

y = 19 * -1

y = -19

Therefore, the value of 'y' is -19.

Final results: a = -18 y = -19
