I have a feeling there should be brackets somewhere

the way it stands .... assuming ∛(3x)

∛(3x) = 3 - 5 - 7

∛(3x) = -9

3x = -729

x = -243

If I take it just the way you typed it

∛3x + 5 + 7 = 3

∛3x = -9

x = -9/∛3 = appr -6.24

PLease let me know where the brackets should be

Of course there's a solution.

∛(3x+5)+7=3

∛(3x+5) = -4

3x+5 = (-4)^3 = -64

3x = -69

x = -23

Check:

∛(-69+5)+7 = ∛-64 + 7 = -4+7 = 3
