4a+3(a+1)=24  perform indicated operations on left side

4a+3a+3=24  combine like terms on left side

7a+3=24  subtract 3 from both sides

7a=21  divide both sides by 7

a=3

Answer:

Option (2) is correct.

a = 3

Step-by-step explanation:

 Given  : equation  4a + 3(a + 1) = 24

We have to solve for a and choose the correct option from the given options.

Consider the given equation  4a + 3(a + 1) = 24

Multiply each term in bracket with 3, we have,

4a + 3a + 3 = 24

Adding 4a and 3a , we have,

7a + 3 = 24

Subtract 3 both sides, we have,

7a + 3 - 3 = 24 - 3

Simplify,

7a= 21

Divide both side by 7, we have,

a = 3

Thus, option (2) is correct.
