Solve each of the following systems of equations graphically: 3x + 2y = 4, 2x – 3y = 7.

Question

Philoid · Accepted Answer

For equation, 3x + 2y = 4

First, take x = 0 and find the value of y.

x	0	4/3
y	2	0

Now similarly solve for equation, 2x - 3y = 7

x	0	7/2
y	- 7/3	0

Plot the values in a graph and find the intersecting point for the solution.

Hence, the solution so obtained from the graph is (2, - 1), which is the intersecting point of the two lines.
