Question

If "a" is a solution to the equation 5 + 6a = 7a-3, then what is the value of 2a?

Answer 1

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
