Answer 1

The given equations are:

Putting in equation we get:

Putting in equation we get:

Use the following table to draw the graph.

	0	3
	3	0

Draw the graph by plotting the two points from table.

Graph of the equation:

Putting in equation we get:

Putting in equation we get:

Use the following table to draw the graph.

	0	6
	12/5	0

Draw the graph by plotting the two points from the table.

The two lines intersect at point P.

Hence, and is the solution.
