It should be 3cm if I did it right
My guess is before the current date but not sure hope that helped and sorry I could not do more and always good luck
You first need to isolate the y
4x+9y=-108
9y=-4x-108 (subtract 4x from both sides)
y=-4/9x-12 (divide both sides by 9)
Then, by using the y=mx+b form, we can tell that the y-intercept is -12 so A
Hope this helps
3r+1w=5
5r+1w=80
System of equations :)
