Solve using substitution:
show work

2x + 5y = -5
x + 3y = 3

answer:

{x,y} = {-6/11,9/11}

step-by-step explanation:

[1]     2x + 5y = 3

  [2]     -x + 3y = 3

// solve equation [2] for the variable   x  

  [2]     x = 3y - 3

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

  [1]     2•(3y-3) + 5y = 3

  [1]     11y = 9

// solve equation [1] for the variable   y  

  [1]     11y = 9  

  [1]     y = 9/11  

// by now we know this much :

    x = 3y-3

    y = 9/11

// use the   y   value to solve for   x  

    x = 3(9/11)-3 = -6/11

solution :

{x,y} = {-6/11,9/11}

answer: i guess 5 units?
