Question

-2q-5=-11 find value of q​

Answer 1

Answer:

q = 3

Step-by-step explanation:

Given: -2q - 5 = -11

⇒ -2q = -11 + 5

⇒ -2q = -6

Multiplying by -1 on both sides we get,

⇒ 2q = 6

⇒ q = 6/2 = 3

Hence the value of q is 3.

Substituting and checking the value:

⇒ -2 ( 3 ) - 5 = - 11

⇒ -6 - 5 = -11

⇒ -11 = -11

Therefore LHS = RHS

Hence Proved !!

Answer 2

Answer:

$= > - 2q - 5 = - 11 \\ \\ = > - 2q = - 11 + 5 \\ \\ = > - 2q = - 6 \\ \\ = > 2q = 6 \\ \\ = > q = \frac{6}{2} \\ \\ = > q = 3$
