for some reason would not let me post the summation right
using weak induction
n
e i = (n(n+1))/2
i=1
(a) (1 point) show that p(1) is true, which completes the base case.
(b) inductive step:
i. (1 point) what is your inductive hypothesis?
ii. (1 point) what are you trying to prove?
iii. (2 points) complete the proof:

2x + 3y = 17 5x + 6y = 32 usibg method if elimination
