Answer:

  1. one
  2. none
  3. one
  4. infinite
  5. none
  6. infinite

Step-by-step explanation:

If you simplify the equations and collect terms, the following can be used to identify the number of solutions:

  a) coefficients of x are different -- one solution

  b) coefficients of x are the same and constants are different -- no solutions

  c) left side the same as right side -- infinite solutions

__

1. different x coefficients -- one solution

2. different constants -- no solutions

3. different x coefficients -- one solution

4. 12x +7 = 12x +7 -- infinite solutions

5. different constants -- no solutions

6. -2x -3 = -2x -3 -- infinite solutions
