Question

9 + 2x = –11 solve this​

Answer 1

Answer:

x= -10

Step-by-step explanation:

2x = -11-9

x = -20

x = -20/2

x =-10

Answer 2

Answer:

We can solve this equation using transposing and non-transposing method

Transposing Method:

9 + 2x = -11

⇒ 2x = -11 - 9

⇒ 2x = -20

⇒ x = -20/2

⇒ x = -10

Non-Transposing Method

9 + 2x = -11

⇒ 9 + 2x - 9 = -11 -9

⇒ 9 - 9 + 2x = -20

⇒ 2x = -20

⇒ 2x/2 = -20/2

⇒ x = -10

VERIFICATION:

Now that we have found out the value of x in the following equation, we have to check whether it's true or not by substituting the value of x as -10

⇒ 9 + 2x = -11

⇒ 9 + 2(-10) = -11

⇒ 9 + (-20) = -11

⇒ 9 - 20 = -11

⇒ -11 = -11

So, our answer is true!!

x = -10

Hope it helped you guys!!
