Answer:
y = ac / (a - b - c)
Step-by-step explanation:
y(a - b) = c(y + a)
Distribute
ay - by = cy + ac
Subtract cy from both sides
ay - by - cy = ac
Factor out y
y(a - b - c) = ac
Divide both sides by (a - b - c)
y = ac / (a - b - c)
Answer:
join the y-related together and the others together
ie -7+1/3y
thats the shortest form one can drill down to, so that should be the answer
Step-by-step explanation:
Answer:
a=4 and b=-1
Step-by-step explanation:
2(4)+3(-1)= 5
