1. Over a period of 6 years (from 1980 to 1986) the house gained a value of 12000 dollars (109k-97k). 12000/6 gives you a rate of 2000 dollars per year. Because the initial price at t=0 is 97000, the function is 97000+2000t

Answer:
step 1: claw (aka distributive property)
multiply 3 by the inside bracket. For example, 3 times 5x= 15x and 3 times negative 2 is negative 6.
15x -6 = 11x
put the x together:
15x - 11x = 6
4x =6
x= 6/4
Finally reduce your answer:
x= 3/2
