Sagot :
Answer:
Nancy is 18 years old right now.
Step-by-step explanation:
Let x be the age of nancy.
Eight years from now will be: x + 8
Nancy will be twice her age 5 years ago: 2(x - 5)
Equate:
x + 8 = 2(x - 5)
x + 8 = 2x - 10
Transpose:
x - 2x = -10 - 8
-x = -18
Divide both sides by -1,
Final Answer: x = 18
