Answer 1

Answer:

Hope it will help you mark me as brain least or thanks me please....

Step-by-step explanation:

Given, x – 2 = 7

By adding 2 to both sides, we get

           x – 2 + 2 = 7 + 2

           ⇒ x = 7 + 2

           ⇒ x = 9

Question 2:

y + 3 = 10

Solution:

Given,y + 3 = 10

By subtracting 3 from both sides, we get

           y + 3 – 3 = 10 – 3

           ⇒ y = 10 – 3

           ⇒ y = 7

Question 3:

6 = z + 2
