geez... don't ask for your homeworks before trying to solve them by your own

i have

alienium · Answer

1. has a range of possible solutions
2. x-1/2y = -1
(x-1/2y) + 1 = 0
2xy-2y+2y = 0
2xy = 0
x or y = 0

2. 2y+x = 8
y+x= 4 (range of solutions)

3. 7 = 1/3y+1
(1/3y+1) - 7 = 0
3y+1-21y+7=0
-18y+8=0
y = 8/-18

4. i don't understand

anonymous · Answer

wait you set it =to 0?

alienium · Answer

yes... if you solve the base case it's simple
just pass the value in the other side and add it to the value of x
