This is a bit of a guess, but I think probably a) +4 and also a) -215
I do not understand what to do , more explicitly sorry :(
48/12 = 24•2/6•2= 24/6= 12•2/3•2= 12/3= 4/1
In simplest form the ratio is

Answer: x=-1 and y= -3
Step-by-step explanation:
Solve for x, x+y=-4
Minus y from both sides so it'll be X=-y-4
Now substitute -y-4 in x-y=2 and solve for y
-y - 4 -y=2
Add like terms, -2y - 4=2
Add 4 to both sides -2y=6
Divide both sides by -2
y= -3
Substitute -3 in x=-y - 4
x=-(-3) - 4
- × (-3)= 3
3 - 4= -1
x= -1
