Question

Select the correct answer.

Jessica is 5 years older than her sister Jenna. Jenna tells her sister that in 5 years, she will be as old as Jessica was 5 years ago. If Jenna’s age is x, which equation represents the situation? How many solutions does the equation have?
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.
(x + 5) + 5 = (x + 5) + 5, which has infinitely many solutions

Answer 1

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

Explanation:

if its wrong im sorry

Answer 2

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

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
