## Discord 3 years ago Solve the system of equations by graphing 3x + 2y = -2 -4x + 5y = -28

Do you have a graphing calculator or other utilities?

2. qpHalcy0n

Or do they want you to actually draw it. (Either way should be fine)

3. Geometry_Hater

You need to graph it and then look for a point of its intersection

4. Discord

Unfortunately I do not have a graphing calculator.

6. qpHalcy0n

I would just use wolframalpha. The way these equations work out, there's no way you'd get an accurate answer on pencil/paper.

or use a free one here http://my.hrw.com/math06_07/nsmedia/tools/Graph_Calculator/graphCalc.html

8. Geometry_Hater

So to start you need to get y by itself in both equations

9. qpHalcy0n
10. qpHalcy0n

If you were using a TI calculator or some similar, you would have to isolate y.

How do I isolate y?

12. qpHalcy0n

Get y by itself in both equations.

13. Geometry_Hater

3x + 2y = -2 Subtract 3x ......2y = -3x -2 Divide by 2........ y= -3/2x - 1 Do the same for the other one

14. Discord

Oh okay. Let me work that out.
