Solve each of the following systems of equations graphically: 3x + 2y = 12 5x – 2y = 4.

Philoid · Accepted Answer

For equation, 3x + 2y = 12

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

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

x	0	4
y	6	0

Now similarly solve for equation, 5x – 2y = 4

x	0	4/5
y	- 2	0

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

Hence, the solution so obtained from the graph is (2,3), which is the intersecting point of the two lines.
