The equation can be solves by adding their two efforts together in a ration equation. See below.
5/x + 15/x = 1
Then give them common denominators and add and solve.
Answer:
<h3>x = 4</h3>
Step-by-step explanation:
102 + 102 + 24x + 24x - 18 - 18 = 360
204 + 48x - 36 = 360
204 + 48x = 360 + 36
204 + 48x = 396
48x = 396 - 204
48x = 192
x = 192/48
x = 4
