Question

Which of the following equations have exactly one solution?

Choose all answers that apply:


A -13x+12=13x+13

B 12x+12=13x+12

C -13x+12=13x-13

D 12x+12=13x-12
Please answer ASAP

Answer 1

Step-by-step explanation:

A

-13x + 12 = 13x + 13

-13x - 13x = 13 - 12

-29x = 1

x = $\frac{-29}{1}$

x = -1

B

12x + 12 = 13x + 12

12x - 13x = 12 - 12

-x = 0

C

-13x + 12 = 13x - 13

-13x - 13x = -13 - 12

-x = -25

x = 25

D

12x + 12 = 13x - 12

12x - 13x = -12 - 12

-x = -24

x = 24

Could the answer be A?

Because here I found the solution of equations A, C, and D.

Whereas the questions must choose the one that has a solution.
