Question

Solve the system of equations:
9x-3y=3
3x+8y=-17

Answer 1

you can solve this system using many methods.

multiply equation 2 by -3 and add the 2 equations to eliminate x

Answer 2

9x-3y=3
-9x-24y=51
=>-27y=54=>y=-2

now substitute y=-2 in one of the equations:
9x+6=3
9x=-3
=>x=-1/3
(x;y)=(-1/3;-2)

Answer 3

so x is -1/3 and y is -2

Answer 4

yes

Answer 5

ok thanks
