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
