Hey there!
Explanation:
First, you had to do is add by 13 from both sides of an equation.
![3a-13+13=47+13](https://tex.z-dn.net/?f=3a-13%2B13%3D47%2B13)
Then, simplify or add by the numbers.
![47+13=60](https://tex.z-dn.net/?f=47%2B13%3D60)
![3a=60](https://tex.z-dn.net/?f=3a%3D60)
Next, you can also divide by 3 from both sides of an equation.
![\frac{3a}{3}=\frac{60}{3}](https://tex.z-dn.net/?f=%5Cfrac%7B3a%7D%7B3%7D%3D%5Cfrac%7B60%7D%7B3%7D)
And finally, simplify and divide by the numbers,
![60/3=20](https://tex.z-dn.net/?f=60%2F3%3D20)
*The answer must have a positive sign.*
![\boxed{a=20}](https://tex.z-dn.net/?f=%5Cboxed%7Ba%3D20%7D)
Hope this helps!
