Answer:

-⅖

Step-by-step explanation:

We need to simplify the given equation and find out the value of a , as ,

=> 3(a-1)+31-11a = 4(2a+3)

=> 3a -3+31-11a = 8a + 12

=> -8a -28 = 8a + 12

=> 16a = -28-12

=> 16a = -40

=> a = -2/5

• Hence the value of a is -⅖ .

Question :-

3 ( a - 1 ) + 31 - 11a = 4 ( 2a + 3 )

____________________

Solution :-

Given Information :-

  • Equation ➢ 3 ( a - 1 ) + 31 - 11a = 4 ( 2a + 3 )

To Find :-

  • The value of 'a'

Calculation :-

⇒ 3 ( a - 1 ) + 31 - 11a = 4 ( 2a + 3 )

Opening the brackets and multiplying the terms, We get,

⇒ 3a - 3 + 31 - 11a = 8a + 12

⇒ -8a + 28 = 8a + 12

⇒ 8a + 8a = - 28 - 12

⇒ 16a = 40

Transposing 16 to Right Hand Side, We get,

⇒ a = [tex] \sf \frac{40}{16} [/tex]

⇒ a = [tex] \sf \frac{-2}{5} [/tex]

____________________

Final Answer :-

  • The value of 'a' is [tex] \bf \frac{-2}{5} [/tex]
