Is the 10 taking away 5 or was it meant to me 10.5 ?
Answer:
so you would replace all r with 2 which is 2+q-2
then replace the q with 6 so it would be: r+6-r
combined both of these to get
2+6-2
which would equal to 6
add the 2 and the 6 to get 8
then subtract 2 to get 6
Im not sure, but i will try to get back to you
800 is 10 times as much as 80
