16y — 13= —157 solve for y

Y= 9

-16y-13=-157
You first want to get the y by itself on one side
So you do:
-16y= -157+13
(since you moved -13 to the other side it becomes positive) then you do
-16y= -144 (when you do -157+13 you get -144)
Then divide -144 by -16
y= -144/-16
So finally, you get:
y= 9

Iwould say false, not positive but if prices went up for both stores, technically there will be less buyers?
