Question

If $x+3y=6$ and $2x-3y=12$ intersect, what is the value of x?

• A. 6

Answer 1

The correct option is A 6
Given: $x+3y=6$ and $2x-3y=12$

Now,
Equation 1: $x+3y=6$

x	y
0	2
6	0

Equation 2: $2x-3y=12$

x	y
0	-4
6	0

Plotting the points and draw the lines on the graph:

From the graph, lines intersect at (6, 0). So, the value of x is 6.
