Question

Solve the system of equations of equations by graphing on your calculator rounded to 3 decimal spaces

y-x=-4
2x+y=3

Answer 1

`x=2.333\\y=-1,667`

Explanation:

we have

`y-x=-4` ----> equation A

`2x+y=3` ----> equation B

Solve the system of equations by graphing

Remember that the solution of the system is the intersection point both graphs

Using a graphing tool

The intersection point is (2.333,-1.667)

see the attached figure

therefore

The solution is

`x=2.333\\y=-1,667`
