Yy =6x−30 =x 2 −18x+114 if (a,b)(a,b)left parenthesis, a, comma, b, right parenthesis

For this case we have the following system of equations:
 
 Equaling both equations we have:
 
 From here, we rewrite the polynomial:
 
 Adding similar terms we have:
 
 Factoring we have:
 
 Therefore, the solution is:
  (multiplicity 2)
 Substituting the value of x in any of the equations we find the value of y:
 
 Therefore, the ordered pair solution is:
 
 
 the value of b is:
