I will try my best to help. If these are quadratic equations, you would use the quadratic formula to solve the equations.
1.) y = -2, y = -1/2
2.) x = 6/10, x = 3
3.) b = 5/4, b = -5
4.) a = -5/3, a = -5/2
5.) x = 1/7
6.) x = 1/7, x =-1/7
If this does not help, comment what we need to solve (factor the equation, etc.)
