set them equal to eachother, you will end up with x8 = 8x 71, solve for x

then what do you do? im confused?
 one year ago

yoyointegrals Group TitleBest ResponseYou've already chosen the best response.0
start by adding 71 to both sides

whats the coefficient?

i would start by subtracting \(x\) from both sides, to put all the terms with \(x\) on the left

satellite73 Group TitleBest ResponseYou've already chosen the best response.1
in other words get \(7x71=8\)

then add 71 to both sides to get \[7x=63\] and finally divide both sides by \&\)
 one year ago

satellite73 Group TitleBest ResponseYou've already chosen the best response.1
that, is , finally divide both sides by \(7\)

airrbae Group TitleBest ResponseYou've already chosen the best response.0
so the answer for x=9?
 one year ago

yoyointegrals Group TitleBest ResponseYou've already chosen the best response.0
correct.
 one year ago

airrbae Group TitleBest ResponseYou've already chosen the best response.0
so how would I find y now since I know x?
 one year ago

satellite73 Group TitleBest ResponseYou've already chosen the best response.1
you replace \(x\) by \(9\) in either equation
 one year ago

airrbae Group TitleBest ResponseYou've already chosen the best response.0
wait, is y=1?

krissywatts Group TitleBest ResponseYou've already chosen the best response.0
set them side by side like this: x8=8x71 subtract 8 on both sides and add 8 to both sides now you should get 7x=63

yw (if you meant me, if not, then yw from everyone )
