Question

2x = 12x - 5y = – 29​

Answer 1

Answer:

{x,y} = {6,7}  

Step-by-step explanation:

[1]    2x = 12  

  [1]    x = 6  

// Plug this in for variable  x  in equation [2]

  [2]    (6) - 5y = -29

  [2]     - 5y = -35

// Solve equation [2] for the variable  y  

  [2]    5y = 35  

  [2]    y = 7  

// By now we know this much :

   x = 6

   y = 7

We are done
