You can
put this solution on YOUR website! 2z + x = 11.5
You didn't tell us what to do with it. Always give
the instructions when you post a problem, so we will
know what to do with it.
Were the instructions "Solve for x"? If so then
2z + x = 11.5
Subtract 2z from both sides:
x = 11.5 - 2z
----------------------------------
Were the instructions "Solve for z"? If so then
2z + x = 11.5
Subtract x from both sides:
2z = 11.5 - x
Divide both sides by 2
2z 11.5 - x
---- = -----------
