Which of the following equations have exactly one solution?

Choose all answers that apply:

A

- 13x + 12 = 13x - 13

12x + 12 = 13x + 12

- 13x + 12 = 13x + 13

12x + 12 = 13x - 12

Answer:

A, B, C, D

Explanation:

You want to know which of these equations have exactly one solution:

  • -13x + 12 = 13x - 13
  • 12x + 12 = 13x + 12
  • -13x + 12 = 13x + 13
  • 12x + 12 = 13x - 12

One solution

An equation in a single variable will have one solution if the variable terms on either side of the equal sign have different coefficients.

A: coefficients are -13 and +13; one solution (x=25/26)

B: coefficients are 12 and 13; one solution (x=0)

C: coefficients are -13 and +13; one solution (x=-1/26)

D: coefficients are 12 and 13; one solution (x=24)

All of the given equations have exactly one solution.
