Respuesta :

Answer:

$2

Step-by-step explanation:

Sandy adds $4 to a certain amount of money she already has saved.

Let the amount she has saved be x.

=> x + 4

Kyle already has 10 times as much money as sandy has saved (10x) but then spends 14$ dollars of his savings.

=> 10x - 14

They both have the same amount of money now:

=> 10x - 14 = x + 4

To get x, collect like terms and simplify:

10x - x = 4 + 14

9x = 18

x = 18 / 9 = $2

This means that Sandy had already saved $2.
