Take out the fruit and you have...
X + X + X = 30
X + Y + Y = 18
X - Z = 2
X + Y + Z(- one stupid ####### banana) = ???
You cannot plug in "Y" for the last equation. You might want to buy an "A".Take out the fruit and you have...
X + X + X = 30
X + Y + Y = 18
X - Z = 2
X + Y + Z = ???
3rd line should be: Y - Z = 2Take out the fruit and you have...
X + X + X = 30
X + Y + Y = 18
X - Z = 2
X + Y + Z = ???
Fixed.Take out the fruit and you have...
X + X + X = 30
X + 4Y + 4Y = 18
X - Z = 2
X + 3 Y + Z = ???
No, it isn't. If you are going to do that, then line 3 should read 4Y - Z = 2.Take out the fruit and you have...
X + X + X = 30
X + 4Y + 4Y = 18
X - Z = 2
X + 3Y + Z = ???
Fixed.
Good catch, I didn't even see that he ha the wrong variable there. I was just looking for Ys.No, it isn't. If you are going to do that, then line 3 should read 4Y - Z = 2.
