Here are the equations with infinitely many solutions:

Equations

-19x-19 = -19x-19

-19x+91 = -19x+91

-19x-38 = -19x-38 and the correct option is B, C, D.

Let's analyze the equations and determine which ones have infinitely many solutions:

Equation 1:

-19x-19 = -19x+19

We can solve this equation by adding 19 to both sides:

-19x = -19x+38

Adding 19x to both sides, we get:

0 = 38

This equation has no solutions, as 0 is never equal to 38.

Equation 2:

-19x-19 = -19x-19

Both sides of the equation are identical, so the equation has infinitely many solutions.

Equation 3:

-19x+91 = -19x+91

Similar to Equation 2, both sides of the equation are identical, resulting in infinitely many solutions.

Equation 4:

-19x-38 = -19x-38

As with Equation 2 and Equation 3, both sides of the equation are identical, leading to infinitely many solutions.

Therefore, the equations with infinitely many solutions are:

-19x-19 = -19x-19

-19x+91 = -19x+91

-19x-38 = -19x-38

Therefore the correct option is B, C, D.
