5x + 2y = 9
2x — Зу = 15
Solve

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

Step-by-step explanation:

[2]    2x = 3y + 15

 [2]    x = 3y/2 + 15/2

// Plug this in for variable  x  in equation [1]

  [1]    5•(3y/2+15/2) + 2y = 9

  [1]    19y/2 = -57/2

  [1]    19y = -57

// Solve equation [1] for the variable  y  

  [1]    19y = - 57  

  [1]    y = - 3  

// By now we know this much :

   x = 3y/2+15/2

   y = -3

// Use the  y  value to solve for  x  

   x = (3/2)(-3)+15/2 = 3

let me know if this helps c:

1. y=-5/2x+9/2

2.not solveable

Step-by-step explanation:

1. move x over (2y=-5x+9) 2.divide both sides by 2, to get y by itself (y=-5/2x+9/2)

2. Error couldn't  solve
