x − 3y = 4
2x + y = 8

0

−4

4

3

Answer 1

How do i do this ? i forgot xD @jim_thompson5910

Answer 2

the answer is 0

Answer 3

why ? :)

Answer 4

for the solution you have to have similar coefficients for either x or y
so if i muiltiply the first equation with 2 the coeff for x become equal now subtraction the equations
we get -7y=0
therefore y=0

Answer 5

ok thanks :)
