Answer 2

Let's solve each equation step by step:

1. a : 6 = 18

To solve for 'a,' we need to isolate it on one side of the equation. We can do this by multiplying both sides by 6:

a = 18 * 6 a = 108

Therefore, a = 108.

2. 8 * y = 16

To solve for 'y,' we need to isolate it on one side of the equation. We can do this by dividing both sides by 8:

y = 16 / 8 y = 2

Therefore, y = 2.

3. c * 5 = 15

To solve for 'c,' we need to isolate it on one side of the equation. We can do this by dividing both sides by 5:

c = 15 / 5 c = 3

Therefore, c = 3.

4. a - 2 - 8 = 5

To solve for 'a,' we need to isolate it on one side of the equation. We can do this by adding 2 and 8 to both sides:

a - 2 - 8 + 2 + 8 = 5 + 2 + 8 a = 5 + 2 + 8 a = 15

Therefore, a = 15.

5. y * 5 = 25

To solve for 'y,' we need to isolate it on one side of the equation. We can do this by dividing both sides by 5:

y = 25 / 5 y = 5

Therefore, y = 5.

6. 2 - x = 18

To solve for 'x,' we need to isolate it on one side of the equation. We can do this by subtracting 2 from both sides:

2 - x - 2 = 18 - 2 -x = 16

To further isolate 'x,' we can multiply both sides by -1 (or divide by -1) to change the sign:

x = -16

Therefore, x = -16.

7. x - 7 = 14

To solve for 'x,' we need to isolate it on one side of the equation. We can do this by adding 7 to both sides:

x - 7 + 7 = 14 + 7 x = 21

Therefore, x = 21.

8. a : 3 - 2 = 19

To solve for 'a,' we need to isolate it on one side of the equation. We can do this by adding 2 to both sides and then multiplying by 3:

(a : 3 - 2) * 3 = 19 * 3 (a : 3) = 57 + 2 (a : 3) = 59

To find 'a,' we need to multiply both sides by 3:

a = 59 * 3 a = 177

Therefore, a = 177.

9. y - 7 = 49

To solve for 'y,' we need to isolate it on one side of the equation. We can do this by adding 7 to both sides:

y - 7 + 7 = 49 + 7 y = 56

Therefore, y = 56.

Final results:

1. a = 108
2. y = 2
3. c = 3
4. a = 15
5. y = 5
6. x = -16
7. x = 21
8. a = 177
9. y = 56
