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.
