If x + x = y, we can tell that 2x = y
ReplyDeleteFrom this, we can substitute it into our next equation
This will give us
2x + 2x + x = a
This means that 5x = a
Now we can substitute both 5x = a and 2x = y into our third and final equation
This will give us:
5x + 2x = z
This gives us an answer of 7x's in a z
