Answer (x,y) (3, -2)
Explanation:
using the 
substitution method
y
=
x
−
5
→
(
1
)
y
=
−
2
x
+
4
→
(
2
)
since both equations are expressed in terms of x we
can equate them
⇒
x
−
5
=
−
2
x
+
4
add 2x to both sides
2
x
+
x
−
5
=
−
2
x
+
2
x
+
4
⇒
3
x
−
5
=
4
add 5 from both sides
3
x
+
5
−
5
=
4
+
5
⇒
3
x
=
9
divide both sides by 3
3
x
3
=
9
3
⇒
x
=
3
substitute this value in 
(
1
)
y
=
3
−
5
=
−
2
As a check
substitute these values into 
(
2
)
right 
=
−
6
+
4
=
−
2
=
 left
⇒
point of intersection 
=
(
3
,
−
2
)
        
             
        
        
        
Answer:
