1. The problem statement, all variables and given/known data Use exact arithmetic to solve the following system: 10-3x-y=1, x+y=0. 2. Relevant equations I know that 10-3=0.001. 3. The attempt at a solution Here's the work: y=-x 10-3x+x=1 x(10-3+1)=1 x=1/(0.001+1)=1/1.001 y=-1/1.001 since y=-x The answer for this problem is (1/1.001, -1/1.001) but this is a Linear Algebra problem. The work that I've shown above are Algebra 1 skills. I must use exact arithmetic to solve the system. How do I do so?
