Answer:
$1575
Step-by-step explanation:
If I bet $25 (And I win, of course!), I will win:
If I win $63 per every $1 bet, then:
63/1 = x/25 ⇒ Solving for 'x':
63*25 = $1575
Finally, if you bet $25 you will win $1575!
<u> 3x + y = 25</u>
To solve for 'y' ...
Subtract 3x from each side: <em> y = 25 - 3x</em>
===========================================
<u>3x + y = 25</u>
To solve for 'x' ...
Subtract 'y' from each side: 3x = 25 - y
Divide each side by 3 : <em>x = (25 - y) / 3 </em>
