Question

Which of the following equations have infinitely many solutions? Choose all answers that apply: a--19x+91=-19x+91

b--19x-38=-19x-38
c- -19x-19= -19x-19
d- -19x-19= -19x+19
PLEASE HELP- RIGHT ANSERS ONLY- WILL MARK BRINLIST FIRST TO ANSER CORRECTLY​

Answer 1

A, B, C

Explanation:

We can start by combining like terms in all of these equations:

A:

-19x + 91 = -19x + 91

-19x = -19x

x = x

A is correct

B:

-19x - 38 = -19x - 38

-19x = -19x

x = x

B is correct

C:

-19x - 19 = -19x - 19

-19x = -19x

x = x

C is correct

D:

-19x - 19 = -19x + 19

We see from here that these are not identifcal equations, so therefore choice A,B and C are correct.
