Remember you can do anything to an eqautoin as long as you do oit to both sides
-5x=15
try to get 1x by itself
remember
(ax)/a=x when a=a
so
-5x=15
get x
divide both sides by -5
remember to flip sign
(-5x)/(-5)=15/(-5)
x=-3
answer is first one
x=-3
First, we subtract 12x from both sides. We then get -4y=-12x+48. We then divide this by -4 on both sides to get the y by itself. We then get that the equation is y=3x-12.
9.82-9.71=.11
.11x100 divided by 9.82 = 1.12%
Answer:
