Answer:

The value of 2a will be: 16

Step-by-step explanation:

Given the equation

5 + 6a = 7a-3

subtract 5 from both sides

5+6a-5=7a-3-5

6a=7a-8

-a=-8

Divide both sides by -1

\frac{-a}{-1}=\frac{-8}{-1}

a=8

As we know that a=8 is the solution to the equation.

Hence, the value of 2a will be:

2a = 2(8)    ∵ a=8

     = 16

Therefore, the value of 2a will be: 16
