Solve for X and Y - Hamada-77 - 01-25-2018 09:09 AM
hello how can i solve this two equations with Hp prime ? Need to solve for X and For Y . see please attachment. Thank you RE: Solve for X and Y - salvomic - 01-25-2018 09:26 AM
You can use the app Solve, then (in Symb) write the equations in E1 and E2; in Num give some guess tries for X and Y and press Solve: X=9, Y=-4 Salvo RE: Solve for X and Y - Arno K - 01-25-2018 10:20 AM
Not to forget the Linear Solver App, you simply enter your 6 numbers and push Solve. Arno RE: Solve for X and Y - salvomic - 01-25-2018 10:48 AM

You could use a graphical approach, using the Advanced Graphing App. The two solutions show up nicely at the intersections of the two expressions: Points (X,Y) = (4,9) and (9,-4) [attachment=5592] -Dale- RE: Solve for X and Y - Arno K - 01-25-2018 11:12 AM

No, I was wrong, did not enlarge that pic, so I did not see that the second equation is quadratic. Arno RE: Solve for X and Y - salvomic - 01-25-2018 11:25 AM

solve({13*x+5*y=97,x^2+y^2=97},{x,y}) |
