Let 3 credit courses = x, 4 credit courses = y
<u>As per given we have following equations:</u>
<u>Solve the system by elimination. Multiply the first equation by 4 and subtract the second one:</u>
- 4(x + y) - (3x + 4y) = 4(18) - 59
- 4x + 4y - 3x - 4y = 72 - 59
- x = 13
The answer is 13
Correct choice is A
