Question

x+5=3x

solve with 8 class formula​

Answer 1

Solve the following equations:

Question 1:

x - 2 = 7

Solution:

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

Solution:

Given,6 = z + 2

By substracting 2 from both sides, we get

6 – 2 = z + 2 – 2

⇒4 = z + 2 – 2

⇒ 4 = z

⇒ z = 4

Question 4:

Solution:

Given,

By subtracting from both sides, we get
