infinitely many

1 solution

Step-by-step explanation:

1. 2.3x-7=-7

2.3x=0

x=0

2. 3x=5+3x

0x=5

x=5/0

That’s undefined

3. 40-4x=4(10-x)

40-4x=40-4x

They both are equal no matter what. So, infinitrly many

4. -7+x=-(x+7)

-7+x=-x-7

2x=0

x=0

1 solution I.e 0

  1-  One solution

                2- No solution

                3- Infinite

               4-  one solution
