Study Notes
Equations and Variables
- The equation given is 2x - 1 + 2x + 1 = 1280
- The equation is simplified by combining like terms: 2x - 1 + 2x + 1 = 2x + 2x - 1 + 1 = 4x = 1280
- The sum of 2x - 1 and 2x + 1 is 4x
- To solve for x, divide both sides of the equation 4x = 1280 by 4
- The value of x is 1280 / 4 = 320
