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)
 
        
             
        
        
        
<span>The coterminal angles of angle A are given by adding k times 360° to it, where k is an integer, positive or negative.
Similarly, all angles that are coterminal with 141° are given by
141° + k * 360° where k is a positive or negative integer.
That is 141° + 360°, 141 + 2*360° , 141+3*360° and so on
and 141° - 360°, 141° -2*360°, 141° - 3*360° and so on.

Answer:
2880
Step-by-step explanation:
(Warning I may have this wrong, and in any way shape or form you get this question wrong i apologize) 
There are 6 faces on a cube, and if each face is 480 square inches you must simply multiply 6x480. 
Hope this helps :)
