A.
x + 5 = (5 − x) − 5, which has one solution
B.
x + 5 = (x + 5) − 5, which has infinitely many solutions
C.
x + 5 = (x + 5) − 5, which has no solution
D.
x + 5 = (5 − x) − 5, which has infinitely many solutions
E.

Answer:

C. x + 5 = (x + 5) − 5, which has no solution

Step-by-step explanation:

Jenna's age                   Jessica's age

today                         x                               x + 5

in 5 years                 x+5

5 years ago                                                   x + 5 - 5

Equality                  x + 5 = x + 5 - 5

=> x + 5 = x

The equation is x + 5 = ( x + 5 ) -5

Answer: its either A or E but im 90% sure its E
