Distribute the 3a^n to all the other values then solve...
(3a^n*a^n)+(3a^n*a^n)+(3a^n*-1)
4a^2n+4a^2n-3a^n=
8a^2n-3a^n

Hello!

We know that the angles in a rectangle are 90°

Since they are 90° then the two separate angles add to 90

4x - 12 + x + 2 = 90

Combine like terms

5x - 10 = 90

Add 10 to both sides

5x = 100

Divide both sides by 5

x = 20

Now we put x into the two angles

x + 2 = ?

(20) + 2 = 22

4x - 12 = ?

4(20) - 12 = ?

80 - 12 = 68

The answers are
x = 20
4x - 12 = 68
x + 2 = 22

Hope this helps!
