Answer:

[A]. a + 2(a – 3) = 15

Step-by-step explanation:

To See which equation is true for the value a = 7 Solve all of it.

Start with [A]

[A] a + 2(a – 3) = 15

7+2(7-3)=15

Hence,this is True.

Next ,[B]

[B] 4a-4(14-a)=24

4(7)-4(24-7)= -40

Hence, this is False.

Then, we have [C]

[C] 2a + 47 = 105

2(7) + 47 =61

Hence, this is False.

Now, We have [D]

[D] 3a+2(a-3)=34

3(7)+2(7-3)=29
Hence, this is False.

Lastly, We have [E]

[E] 4a-2a=18

4(7)-2(7)=14

Hence, this is False.

Thus, Correct Answer = [A].a + 2(a – 3) = 15
