2. Solve each given equation and show your work. Tell whether it has one solution, an infinite number of
solutions, or no solutions, and identify each equation as an identity, a contradiction, or neither.
(c) 6x + 4x - 6 = 24 + 9x
(d) 25 - 4x = 15 - 3x + 10 - X
(e) 4x + 8 = 2x + 7 + 2x - 20

Answer:

The answer to your question is below

Step-by-step explanation:

c)  6x + 4x - 6 = 24 + 9x

     6x + 4x - 9x = 24 + 6

     x = 30                       This equation has one solution, it's an identity

d) 25 - 4x = 15 - 3x + 10 - x

    -4x + 3x + x = 15 + 10 - 25

   0 = 0                           It has infinite number of solutions, it is an identity

e)  4x + 8 = 2x + 7 + 2x - 20

    4x - 2x - 2x = 7 - 20 + 8

                  0 = -5          It has no solution it is a contradiction
