Hi there!
x - 3y = 9
x = 9 + 3y
-4x + y = 8
-4(9+3y) + y = 8
-36 - 12y + y = 8
-36 - 11y = 8
-11y = 44
-y = 4
y = -4
x - 3y = 9
x - 3(-4) = 9
x + 12 = 9
x = 21
So, your answers are y = -4 and x = 21.
Hope this helps!
Ratio 5:4
Total shares = 5+4 = 9
then to find for 1 share = 54/9 = 6
So Sam share = 6 x 5 = 30
Bethan share = 6 x 4 = 24
Poof: 30+24 = 54
Answer:
y = m x + b standard form of equation for straight line\
m = (y2 - y1) / (x2 - x1) = (20 - -8) / 17 - 1) = 28 / 16
m = 7 / 4
