I’m not sure if you want the answer or how to do i’ll just give you both.
multiply the bottom by -4. then it should look like:
8x-6y=-6
-8x+16y=56
then cancel out the x’s and add/subtract the others, giving you: -2y=50. then divide 50 by -2 giving you: y=-25. then find x. plug in y to one of the equations. i usually do the one that hasn’t been messed with. 8x-6(25)=-6. then solve it like a normal two-step equation.
so the answer is: (18,-25)
your almost right check once and you wil get especially alternate angles

Rearrange 19 × 8 × c-(3)>0
Pull out the like terms (factors) 16- 8c = -8 × (c-2)
Divide each side by. -8
Add 2 to each of the sides
So, C<2 would be your result
