you could either multiply straight away or you could simplify right then so that you wouldn't have to it later.
20/5 * 5/2
your answer would be 10 either way
Answer:
3 Credit Courses = 37
4 Credit Courses = 11
Step-by-step explanation:
1. Set up 2 equations:
3x + 4y = 155
x + y = 48
2. Simplify the second expression for x by subtracting y from both sides
x = 48 - y
3. Substitute 48 - y for x
3(48-y) + 4y = 155
4. Simplify the expression by multiplying by 3
144 - 3y +4y = 155
5. Subtract 144 from both sides and subtract 3y from 4y
y = 11 = 4 Credit Courses
6. Substitute y for equation 2
x = 48-11
7. solve for x
x = 37 = 3 Credit Courses
