one at a time is much better

OpenStudy (anonymous):

scratch that SUBTRACT 8 is better

OpenStudy (anonymous):

I think its C

OpenStudy (anonymous):

OpenStudy (anonymous):

takes a couple steps did you subtract 8?

OpenStudy (anonymous):

dang \[k+7=3\] or \[k+7=-3\]

OpenStudy (anonymous):

solve both, by subtracting \(7\) from both sides to get your two answers

OpenStudy (anonymous):

OpenStudy (texaschic101):

not D k + 7 = 3 k = 3 - 7 k = ? k + 7 = -3 k = -3 - 7 k = ? try again

OpenStudy (anonymous):

OOO its A!
