Step-by-step explanation:

Determine the time they both arrive together
To do this, we simply determine the common multiple of both numbers:
Start by listing the multiples of 4;
Next, list the multiples of 10
<em>Their common multiple is: 20</em>
<em>Hence, they'll both arrive at 20 minutes</em>
3 hours = 60 x 3 minutes = 180 mins.
Total windows = 30.
So, total time = 30 x 180
= 5400mins
= 90 hours
Subtract 10x
10x + y = -19
10x + 3y = -17
You would get:
-2y = -2
Two negatives make a positive number! Divide
y = 1
Plug in
10x + (1) = -19
10x = -20
Divide
x = -2
Your solutions are
x = -2
y = 1
