Solution for -m+b=-9;m+b=-4 system of equations: 


  • /| b-m+9 = 0| b+m+4 = 0
  • We try to solve the equation: b-m+9 = 0
  • b-m+9 = 0 // - 9-m
  • b = -(9-m)
  • b = m-9
  • We insert the solution into one of the initial equations of our system of equations
  • We get a system of equations:
  • /| m+m-9+4 = 0| b = m-9
  • 2*m-5 = 0 // + 5
  • 2*m = 5 // : 2
  • m = 5/2
  • We insert the solution into one of the initial equations of our system of equations
  • For b = m-9: 
  • b = 5/2-9
  • b = -13/2
  • We get a system of equations:
  • /| b = -13/2| m = 5/2
