Answer:

Solve for a:
a = (b+2)/(3)

Steps:

b = -2 + 3
a

Swap sides so that all variable terms are on the left-hand side.

-2 + 3
a = b

Add 2 to both sides.

3
a = b + 2

Divide both sides by 3.


(3a)/(3) = (b +2)/(3)

Dividing by 3 undoes the multiplication by 3.


a = (b+2)/(3)

Solve for b:

b = 3
a - 2

Hope this helps and have a Great day! =D
