Answer:

Step-by-step explanation:

CBSE Ncert Solution for Class 8 - Maths - Linear Equations in One Variable. ... x = 2. Question 5: Solve the following: 6x = 12. Answer: Given, 6x = 12. => 6x/6 .

Answer 2

Step-by-step explanation:

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
