First, make sure that all the variables are in one side. The first equation is gonna be x-y=3
Second, we are going to eliminate the y because it is much easier, but you can also eliminate the x
We have to add both equation because the y in the first equation is negative and in the second equation it’s positive.
We are left with 3x=9
Therefore, x=3
Last, substitute x= 3 in one of the equations
Y=6
P.O.I is (3,6)
Answer:
Discount selling price= $172.5
Step-by-step explanation:
Giving the following information:
Selling price= $230
Discount rate= 25%

Discount selling price= $172.5
Nothing, it's just your foot. So if going to ask a question make it reasonable. OK?
-14,-10,-6,-2,2,6
Answer by Mimiwhatsup: I could easily subtract -14 from -10 to find out the sequence so they are adding four each time. That means the pattern will continue going on like this 10, 14, 18, 22 and so forth.
