20 Points + Brainlest Determine if the following system of equations has no solutions, infinitely many solutions or exactly one solution.
-x+5y=-7
-3x +14y=-18

One solution:(-8,-3)

Step-by-step explanation:

 x = 5y + 7

Plug this in for variable  x  in equation [2]

  [2]    -3•(5y+7) + 14y = -18

  [2]     - y = 3

Solve equation [2] for the variable  y  

  [2]    y = - 3  

By now we know this much :

   x = 5y+7

   y = -3

Use the  y  value to solve for  x  

   x = 5(-3)+7 = -8  

Solution :

{x,y} = {-8,-3}

Hope this helps plz mark brainliest if correct :D

yes because there is exactly one y value for every x value

for function there can't be more than one value for every x value
