Answer:

1 solution

No solution

Infinitely many solutions

1 solution

Step-by-step explanation:

2.3x - 7 = -7

2.3x = 0

x = 0

1 solution

3x = 5 + 3x

0 = 5

No solution

4(10 - x) = 40 - 4x

40 - 4x = 40 - 4x

Infinitely many solutions

-7 + x = -(x + 7)

-7 + x = -x - 7

2x = 0

x = 0

1 solution
