7x - 1 + 2x - 1 = 7
9x - 2 = 7
9x = 9
x = 1
Combine like terms and solve :)

Answer:
(27,000 - 22,900)/27,000 = 0.1519 or 15.19% decrease in price.
Step-by-step explanation:
See that odd number are in a Aritmetic progression with a1 = 1 and r = 2
30th number of sequence is given by:
Now you can calculate the sun by:
Y=-1/2x-3
You can rewrite the equation “y=mx+b” and fill in what you know. So your equation would look like y=-1/2x+b when filling in what you know. Now you can take the (x,y) coordinates that you were given and plug them into the equation and solve for b. So now it would be -5=-1/2(4)+b
