Gabe took one 3 credit course and three four credit course.

Equation

Equation is used to show the relationship between two or more numbers and variables.

Let x represent the number of 3 credit courses and y represent the number of 4 credit courses.

He plans to take 4 courses earning 15 credits, hence:

  • x + y = 4   (1)
  • 3x + 4y = 15 (2)

Solving equation 1 and 2 simultaneously gives:

x = 1, y = 3
