The answer is 20.5 try it good luck
We are given
First equation:

we can use formula

slope is m=1
y-intercept is b=-1
Second equation:

we can use formula

slope is m=-2
y-intercept is b=5
Graph:
We can see that
both curves intersect at (2,1)
so, solution is x=2 and y=1.................Answer
Answer: -12.81% decrease
Step-by-step explanation:
1678-1463/1463 * 100 = -12.8128
6 times 12 is 72 so 14 times 12 would be 168 if that is what you are looking for. So for that y=168 :-)
