thats readable. cbrt(3x+4) is workable as well; or 3rt(arg)

OpenStudy (asnaseer):

\[\sqrt[3]{3x+4}+6=7\]\[\sqrt[3]{3x+4}=7-6=1\]\[3x+4=1^{3}=1\]\[3x=1-4=-3\]\[x=-3/3=-1\]

OpenStudy (amistre64):

subtract 6 from each side; cube it all to undo the cbrt and finish off to get to the x

OpenStudy (amistre64):
