Question

The system of equations may be solved by hand calculation or by using the crossing-graphs method.Solve the following system using the crossing-graphs method.3x + 2y = 64x – 3y = 8(x, y) = (____,____)

Answer 1

Solve the following system using the crossing-graphs method.

3x + 2y = 6

4x – 3y = 8

we know that

When solving a system of equations by graphing, the solution is the intersection point both graphs

so

using a graphing tool

see the attached figure to better understand the problem

please wait a minute

The solution is the point (2,0)

therefore

(x,y)=(2,0)
