A college some completed some courses worth 3 credits and some courses worth 4 credits. The students earned a total of 59 credit

Law Incorporation [45]

The student completed 13 courses with 3 credit hours.

Step-by-step explanation:

Total credit hours = 59 credits hours

Total courses = 18

Let,

3 credit hours courses = x

4 credit hours courses = y

According to statement;

x+y=18 Eqn 1

3x+4y=59 Eqn 2

Multiplying Eqn 1 by 3

$3(x+y=18)\\3x+3y=54\ \ \ Eqn\ 3$

Subtracting Eqn 3 from Eqn 2

$(3x+4y)-(3x+3y)=59-54\\3x+4y-3x-3y=5\\y=5$

Putting y=5 in Eqn 1

$x+5=18\\x=18-5\\x=13$

The student completed 13 courses with 3 credit hours.
