From x + y = 5,
If x = 0
0 + y = 5
y = 5
Therefore (0,5)
If x = 1
1 + y = 5
y =5 - 1
y = 4
Therefore (1,4)
Draw a graph for this
And
From 3x - 2y = 0
If x = 0
3 (0) - 2y = 0
0 - 2y = 0
-2y = 0
y = 0/-2
y =0
Therefore (0,0)
If x = 2
3 (2) -2y = 0
6 - 2y = 0
-2y = -6
y = -6/-2
y = 3
Therefore (2,3)
Draw a graph for these points
And the point of intersection is (2,3)
