Answer:

>>> a = -55

Explanation:

Given Equation ,


  • \sf{ - 3 = 2 + (a)/(11) }

We have to find ,

  • Value of a

Solution :


\dashrightarrow \: \: \: \sf{ - 3 = 2 + (a)/(11) }

or , we can write it as :


\dashrightarrow \: \: \: \sf{2 + (a)/(11) = - 3 }

Step 1 : Subtracting 2 on both sides :


\dashrightarrow \: \: \: \sf{ \cancel{2} + (a)/(11) - \cancel{2} = - 3 - 2 }

We get ,


\dashrightarrow \: \: \: \sf{ (a)/(11) = - 5 }

Step 2 : Multiplying both sides with 11 :


\dashrightarrow \: \: \: \sf{ \frac{a}{ \cancel{11}} * \cancel{11} = - 5 * 11 }

We have ,


\dashrightarrow \: \: \: \underline{ \boxed{ \sf{ \bold{a = - 55}}}} \: \: \: \bigstar

  • Therefore, value of a is "-55".

Verification :-

For verifying our answer we have to substitute value of a in given equation and after solving it if Left side is equal to Right side then we can say that our answer is correct.


\longmapsto \: \: \: \sf{ - 3 = 2 + (a )/(11) }

Substituting value of a as -55 :


\longmapsto \: \: \: \sf{ - 3 = 2 + \cancel{ ( - 55 )/( \: \: \: 11) }}


\longmapsto \: \: \: \sf{ - 3 = 2 - 5 }


\longmapsto \: \: \: \sf{ - 3 = 2 - 3 }


\longmapsto \: \: \: \sf{ LHS = RHS }


\longmapsto \: \: \: \sf{Hence , Verified }

  • Therefore, answer is correct.

Hope, it'll help you!! :)

Answer:

a = -55

Explanation:

We're asked to solve the following equation:


\sf{-3=2+\cfrac{a}{11}}

Begin by subtracting 2 from both sides:


\sf{-3-2=\cfrac{a}{11}}


\sf{-5=\cfrac{a}{11}}

Next, multiply both sides by 11:


\sf{-5*11=a}


\sf{-55=a}

Therefore, a = -55.
