Solution for 7x+5y=-25;5x-2y=10 system of equations: 


  • /| 7*x+5*y+25 = 0| 5*x-(2*y)-10 = 0
  • We try to solve the equation: 7*x+5*y+25 = 0
  • 7*x+5*y+25 = 0 // - 7*x+25
  • 5*y = -(7*x+25) // : 5
  • y = (-(7*x+25))/5
  • We insert the solution into one of the initial equations of our system of equations
  • We get a system of equations:
  • /| 5*x-(2*((-(7*x+25))/5))-10 = 0| y = (-(7*x+25))/5
  • (-1*2*(-7*x-25))/5+5*x-10 = 0
  • 39/5*x-10+10 = 0
  • 39/5*x = 0
  • 39/5*x = 0 // : 39/5
  • x = 0
  • We insert the solution into one of the initial equations of our system of equations
  • For y = (-(7*x+25))/5: 
  • y = (-(0*7+25))/5
  • y = (-(0+25))/5
  • y = -25/5
  • y = -5
  • We get a system of equations:
  • /| y = -5| x = 0
