Question

Solve the system of equations:
3x-2y=-1
3x-4y=9

Answer 1

you subtract i think its 2y- (-4y) which equals 6y and then subtract -1 -9 to get negative 10 so the answer is 6y=-10 and then divide so y=-5/3 Hopefully!! :p

Answer 2

you can multiply the first equation by -2 and get
\[-6x+4y=2\]
\[3x-4y=9\] hten add to get
\[-3x=11\] so
\[x=-\frac{11}{3}\]

Answer 3

then replace x by
\[-\frac{11}{3}\] and solve for y you will get
\[y=-5\]

Answer 4

thank you
