The set up for each problem.

Question 1

Let x = invested at 8%.

Let 6000 - x = invested at 12%.

What I invested at 8% + what I invested at 12% = 600.

0.08x + 0.12(6000 - x) = 600

Yes?

Question 2

Let x = Norman's invested amount at 5%.

Let 0.07x = what he invested at 7%.

Equation:

0.05x + 2(0.07x + 500) = 187

Yes?
