Which of the following equations have exactly one solution? Choose all answers that apply:
(Choice A)
A
6x-15=6x+15

(Choice B)
B
6x-6=15x+15

(Choice C)
C
6x-6=6x+15

(Choice D)
D
6x+15=6x+15

B) 6x - 6 = 15x + 15

Step-by-step explanation:

To find our answer, we need to first work out each equation.

A) 6x - 15 = 6x + 15

First, cancel out the equal terms.

6x - 6x - 15 = 15

-15 = 15

This statement is false.

B) 6x - 6 = 15x + 15

-9x = 21

x = -7/3

This statement has one solution.

C) 6x - 6 = 6x + 15

-6 = 15

This statement is false.

D) 6x + 15= 6x + 15

15 = 15

This statement has infine solutions.
