// by bell /* Challenge by JIANMIN CHEN: Solving System Of Equations A system of equations is basically two linear equations: 3x + 5y = 9 2x + 3y = 5 Write a program that takes in input like this: 3 5 9 2 3 5 The first number in each row is the coefficient for x, the second number is the coefficient for y, and the last number is the constant(meaning it's basically already in standard form). Solve the system of equations and return the value of x and y in a ordered pair like this: (2, -3) Note that the input may include decimal numbers. This does pose a problem for statically typed programming languages(attempting to use a double in Java for me returns decimal numbers even for whole number solutions), so feel free to print the rounded solution and the exact number solution. Input: -2 10 2 5 -25 3 Output: Infinite Solutions Input: 3 9 -6 -4 -12 8 Output: No Solutions */ #include #include #include #include #include using namespace std; int EqSolver(double d,double e,double f,double a,double b,double c){ double x,y; if(fabs(a)<0.0001){ y=c/b; x=(f-e*y)/d; } cout<<"x= "<v={3,5,9,2,3,5}; // double a=2.,b=-3.,c=-2.,d=4.,e=1.,f=24.,t; //x= 5, y= 4 double a=-2.,b=10.,c=2.,d=5.,e=25.,f=3.,t; //x= 5, y= 4 cin>>a>>b>>c>>d>>e>>f; cout<0.0001&&fabs(b)>0.0001&& fabs(d)>0.0001&&fabs(e)>0.0001){ cout<<"triangulate matrix"<
