Question 187303: Please help me solve this linear equation problem !!!
A teacher gives out a test 0f 30 problems. Each computation problem is worth 3 points.Each word problem is worth 5 points. The total of points you can receive on the test is 110 points. How many computation problem are there?

You can put this solution on YOUR website!
Let c = computation problem
Let w = word problem
c + w = 30...Equation A
3c + 5w = 110...Equation B
This is a system of linear equations in two variables.
Can you solve this system for c and w now?
