PLEASE I NEED HELP WITH THIS ANSWER

a) x = -2/3    y = -26/3 or -8 2/3

b) x = 12      y = 5

Step-by-step explanation:

a) since both equations begin with 'y =' you can set them equal to each other

4x - 6 = x - 8

3x = -2

x = -2/3

sub x value to find y:

y = 4(-2/3) - 6

   = -8/3 + (-18/3)

   = -26/3  

rick has $1400 and sally has $1500

step-by-step explanation:

to find amount of money rick has after 10 years :

principal = $1000 , time = 10 years , rate = 4% annually

to find amount of money sally has after 10 years :

her friend gives to pay her $50 per year, therefore money she has after 10 years = 50 × 10 = $500

also, sally gets $1000 after 10 years,

therefore, total amount of money sally has after 10 years = 500 + 1000 = $1500

so, after 10 years : rick has $1400 and sally has $1500
