Solution for -9x-2y=-55;-6x-4y=-26 system of equations: 


  • /| 55-9*x-(2*y) = 0| 26-6*x-(4*y) = 0
  • We try to solve the equation: 55-9*x-(2*y) = 0
  • 55-9*x-2*y = 0 // - 55-9*x
  • -2*y = -(55-9*x) // : -2
  • y = (-(55-9*x))/(-2)
  • y = (55-9*x)/2
  • We insert the solution into one of the initial equations of our system of equations
  • We get a system of equations:
  • /| 26-(4*((55-9*x)/2))-6*x = 0| y = (55-9*x)/2
  • (-1*4*(55-9*x))/2-6*x+26 = 0
  • 12*x-110+26 = 0
  • 12*x-84 = 0
  • 12*x-84 = 0 // + 84
  • 12*x = 84 // : 12
  • x = 84/12
  • x = 7
  • We insert the solution into one of the initial equations of our system of equations
  • For y = (55-9*x)/2: 
  • y = (55-9*7)/2
  • y = (55-63)/2
  • y = -8/2
  • y = -4
  • We get a system of equations:
  • /| y = -4| x = 7
