Input as many equations you want, between the square brackets, separated by a commas (" , ") and the variables used ( between the square brackets, separated by commas), in the boxes below. See examples below.
Examples:
1) The equations : [x+y+z=2, x*y*z=9, x*y-z=0]
The variables: [x,y,z]
2) The equations : [3*a+2*b-c = 1, 2*a-2*b+4*c = -2, -a+(1/2)*b-c = 0]
The variables: [a,b,c]
3) The equations : [x1+x2+x3+x4 = 9, 2*x1+x2-x3/2+x4 = 4, 3*x1-x2/2+3*x3-x4 = 12, x1+x2-x3+x4 = 10]
The variables: [x1,x2,x3,x4]
