You are given the system of equations:x=25-y,5x +y =10. Which method of solving systems of equations is the best method to use?

the two may have that, even a breakdown is probably offered

isaiah walks 3 miles due north, turns and then 5 miles due east. how far is he from his starting point?

a^2 + b^2 = c^2

let c = distance from starting point.

(3)^2 + (5)^2 = c^2

9 + 25 = c^2

34 = c^2

sqrt{34} = sqrt{c^2}

sqrt{34} = c

answer: (3,11) is your answer.
