I will do the second:
2x-6y=24
-3x+y=-2
multipy the second equation by 6 to eliminate the y's.
2x-6y=24
-18x+6y=-12
add the equations
-16x=12
x=-3/4
then solve for y by putting that x back into one of the equations.
I will be happy to check your work on the others.
i dont think thats write cuz they show me another way
