Question 923368
3x-y=7  0r y ={{{3x-7}}}
Y + 2x=8 
(3x-7) + 2x = 8
5x = 15
x = 3  and y = 2 {{{9-7}}}
(3,2) the solution to this System
..........
Elimination
3x - y = 7
<u>2x + y = 8</u>
5x = 15, x = 3  and y = 2
.........
Graphing
y = 3x-7 P(0,-7) and (2,-1) on this line.. Plot points and connect with Line
y = -2x + 8  P(0,8) and P(4,0) on this line....Plot points and connect with Line
Intersection: P(3,2)
