Answer 2

The solution to the equation 3a-7(3-a)=5 is a=13/5.

Let's solve for a in the equation:

3a-7(3-a)=5

We can solve the equation by rearranging the terms, distributing, combining like terms, adding/subtracting to both sides, dividing both sides by the same factor, and simplifying.

Steps to solve:

Rearrange terms:

3a-7(-a+3)=5

Distribute:

3a+7a-21=5

Combine like terms:

10a-21=5

Add/subtract to both sides:

10a-21+21=5+21

Simplify:

10a=26

Divide both sides by the same factor:

10a/10=26/10

Simplify:

a=13/5
