1. Solve for x: 3(2x - 5) + 4 = 7x - 10

2. Solve for y: (2y + 1)/3 = (y - 2)/2

3. The solutions to the equation x² - 5x + 6 = 0 are x = or x = .

4. To solve 2x² + 7x - 4 = 0 using the quadratic formula, the values for a, b, and c are a = , b = , and c = . The solutions are x = or x = .

5. Which of the following is the solution for x in the equation 1/(x+1) + 2/(x-1) = 3/(x²-1)?
