Answer:
<em>Tadeo Volunteered for 12 hours while Dylan volunteered for 2 hours</em>
Step-by-step explanation:
Let the total number of hours Tadeo volunteered be x
Let the total number of hours Dylan volunteered be y
If together they volunteer at a total of 14 hours, then;
x + y = 14 ...... 1
If<em> </em>Tadeo Volunteered at the library six times as many hours over the weekend as Dylan, then;
x = 6y
Substitute x = 6y into 1;
6y + y = 14
7y = 14
y = 14/7
y = 2
Since x = 6y
x = 6(2)
x = 12
<em>Hence Tadeo Volunteered for 12 hours while Dylan volunteered for 2 hours</em>
