the answer is b, 6
if x=8 then you need to plug in 8 for your in the equation, so you’d have 2(8) - y = 10
you’d get: 16 - y = 10
you’d then subtract 16 from both sides to get -y alone
so now you have -y = -6
you can’t have a -y so you’ll have to divide -1 from both sides
you’ll end up with y=6, which is your answer
