Answers
y=0
2x+6=0
x=-6/2 =-3
2(0)+y+6=0
y=0
3(0)-2y-12=0
-2y=+12
y=-6
GIVEN : y=6-3x
y=4-x
TO FIND Solution using graphical method.
SOLUTION: As we know,
The values of x and y are interrelated.
Now,
Taking up equation 1 ( y = 6-3x )
Firstly,
Putting up x = 0
Therefore, y = 6 - 3(0)
y = 6 - 0
y = 6
The first point of the solution is (0,6)
Secondly,
Putting up y = 0
Therefore, 0 = 6 - 3x
3x = 6
x = 2
The second point of the solution is (2,0)
Plot both the points on the Graph and connect them to make a line.
Now,
Taking up equation 2 ( y = 4 - x )
Firstly,
Putting up x = 0
Therefore, y = 4 - 0
y = 4 - 0
y = 4
The first point of the solution is (0,4)
Secondly,
Putting up y = 0
Therefore, 0 = 4 - x
x = 4
x = 4
The second point of the solution is (4,0)
Plot both the points on the Graph and connect them to make a line.
The Intersecting point of both the lines on the graph can be recognized as the solution for the equations.
