Question

2x+4(x+1)+6(x+2)=160​

Answer 1

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

          

          

Question 5:

6x = 12

Solution:

Given,6x = 12

After dividing both sides by 6, we get

          

Question 6:



Solution:

Given, 

After multiplying both sides by 5, we get

          

Question 7:



Solution:

Given, 

By multiplying both sides with 3, we get

          

After dividing both sides by 2, we get

          

Question 8:



Solution:

Given, 

After multiplying both sides by 1.5, we get

          

Question 9:

7x – 9 = 16

Solution:

Given,7x – 9 = 16

By adding 9 to both sides, we get

          

After dividing both sides by 7, we get

          

Question 10:

Solution:

Given,14y – 18 = 13

By adding 8 to both sides, we get

14y – 8 + 8 = 13 + 8

⇒ 14y = 21

After dividing both sides by 14, we get

          

Question 11:

17 + 6p = 9

Solution:

Answer 2

Answer:

The value of x is 12

Step-by-step explanation:

2x+4(x+1)+6(x+2)=160

2x+4x+4+6x+12=160

12x+16=160

12x=160-16

12x =144

x=144/12

x=12
