Answer:
1) (-6,-9)
times the top equation buy -4 so you cancel out the y
so it be -8x+4y=12 no cancel out the y's
so it be -8x=12 and 5x=6
now combined like terms to get -3x= 36
x = -6 now go plug that back in one of the equations to get y
y = -9
2) (-2,-5)
now on this one you going to substitute y= (2x-1) for y in the otheir eqaution
so it look like 3x-(2x-1)=-1
do your combining of like terms and your division & you get x = -2
now plug x in to y=2x-1 to get y = -5
