Need answer ASAP The age of nicole is 3 times of christine now after five years nicole will be twice as old as krisin How old are they now

Nicole is now 15 years old

Christine is now 5 years old

Step-by-step explanation:

x = age Nicole

y = age Christine

x = 3y

x+5 = 2×(y+5) = 2y + 10

3y + 5 = 2y + 10

y + 5 = 10

y = 5

x = 3y = 3×5 = 15

answer:

when they are equal, y=y, so we can say:

x^2+5x-2=x+1   subtract x from both sides

x^2+4x-2=1   add 2 to both sides

x^2+4x=3, now add half the linear coefficient squared, (4/2)^2=4

x^2+4x+4=3+4 now the left side is a perfect square

(x+2)^2=7   now take the square root of both sides

x+2=±√7   subtract 2 from both sides

x=-2±√7

x=-2+√7 and -2-√7

y=x+1 the two points where these equations are equal are:

(-2-√7, -1-√7) and (-2+√7, -1+√7)

or approximately:

(-4.65, -3.65) and (0.65, 1.65)
