Solution for -7x-2y=-6;4x-3y=7 system of equations: 


  • /| 6-7*x-(2*y) = 0| 4*x-(3*y)-7 = 0
  • We try to solve the equation: 6-7*x-(2*y) = 0
  • 6-7*x-2*y = 0 // - 6-7*x
  • -2*y = -(6-7*x) // : -2
  • y = (-(6-7*x))/(-2)
  • y = (6-7*x)/2
  • We insert the solution into one of the initial equations of our system of equations
  • We get a system of equations:
  • /| 4*x-(3*((6-7*x)/2))-7 = 0| y = (6-7*x)/2
  • (-1*3*(6-7*x))/2+4*x-7 = 0
  • 29/2*x-9-7 = 0
  • 29/2*x-16 = 0
  • 29/2*x-16 = 0 // + 16
  • 29/2*x = 16 // : 29/2
  • x = 16/29/2
  • x = 32/29
  • We insert the solution into one of the initial equations of our system of equations
  • For y = (6-7*x)/2: 
  • y = (6-7*32/29)/2
  • y = (6-224/29)/2
  • y = -50/29/2
  • y = -25/29
  • We get a system of equations:
  • /| y = -25/29| x = 32/29
