The equation would be 2n x 2 = 3n - 1/2.
So, combine like terms to make it 4n = 3n - 1/2. Subtract to get n = -1/2.
Your answer is -1/2.
If you add 5x to 2x+2 you will get 7x+2. You would set this equation equal to 80, so it would be 7x+2=80. When you solve this you will get 11.1428571429, which can be rounded to 11, 11.1, or 11.14, whichever you prefer.
