Answer 8

let y=the spurs

Answer 10

or that ^^^

Answer 11

x+y=217
x=y+7

substitute the second equation into the first equation:
(y+7) + y = 217

now you have 1 equation with 1 variable. I'm sure you can take it from here...

Answer 12

it does not turn to y^2... just get rid of the parenthesis and combine like terms:
(y+7) + y = 217
y + 7 + y = 217
2y + 7 =217

can you take it from that last step?
