Answer:
Solve for a: [tex]a = \frac{b+2}{3} [/tex]
Steps:
b = -2 + 3[tex]a[/tex]
Swap sides so that all variable terms are on the left-hand side.
-2 + 3[tex]a[/tex] = b
Add 2 to both sides.
3[tex]a[/tex] = b + 2
Divide both sides by 3.
[tex]\frac{3a}{3} = \frac{b +2}{3} [/tex]
Dividing by 3 undoes the multiplication by 3.
[tex]a = \frac{b+2}{3} [/tex]
Solve for b:
b = 3[tex]a[/tex] - 2
Hope this helps and have a Great day! =D
