Solving a System of Equations with Three Unknowns
  SOLVING A SYSTEM OF EQUATIONS WITH TWO UNKNOWNS
Let’s solve for x & y when the two equations are:
  • 2x + 3y = 19
  • 5x + 2y = 20
Multiply the top equation by 5 and the bottom equation by -2 so when you add the two equations, the x terms drop out.
Two equations
