Adrian is x years old. benny is 7 years younger than adrian. in 5 year's time, benny will be twice the age of celine. how old is celine now in terms of x.

Step-by-step explanation:

Set up a table to compile the information provided.

We want to find Celine's age today (y) so use the "Benny in 5 years" equation to solve for y.

(x - 7) + 5 = 2(y + 5)

x - 2 = 2y + 10

x - 12 = 2y

answer:   x = 3 + √11     and     x = 3 - √11

step-by-step explanation:

x² - 6x + 9 = 11

(x - 3)² = 11

x - 3 = ±√11

    x = 3 ± √11

x = 3 + √11     and     x = 3 - √11
