Answer:
B and D
Step-by-step explanation:
When both sides of an equation are same then the equation has infinitely many solutions
x-3x=-2x+4
Both sides are not same.
LEts simplify the left hand side. cancel out 3 at the top and bottom
x- x = 0
0=0 , so the equation have infinitely many solutions.

Both sides are not same , so does not have infinite solutions
Cancel out 3 at the top and bottom
3x + 2 -x = 2+2x
2x+2 = 2+2x
Both sides are same , so the equation have infinitely many solutions.

Both sides are not same .
