Sandy is upgrading her Internet service. Fast Internet charges $60 for installation and $50.45 per month. Quick Internet has free installation but charges $57.95 per month.

The equation that represents this scenario is 60 + 50.45x = 57.95x

• True.

• False.

Simplify and tell whether the equation has one, zero or infinite solutions.

2(3x - 6) = -12 + 6x

• x = 4; One Solution

• x = -x; No Solution

• 0 = 0; Infinite Solutions

• x = 0; One Solution

Select the answer choice that represents infinite solutions.

• x = x

• x = 4

• x = y

• x= -x
