Which value is the solution of
[tex] \sqrt[3]{3x} + 7 = 4[/tex]


A.-9
B.-1
C.3
D.19​

Answer :

Answer:

A

Step-by-step explanation:

[tex]\sqrt[3]{3x}[/tex] + 7 = 4 ( subtract 7 from both sides )

[tex]\sqrt[3]{3x}[/tex] = - 3 ( cube both sides to clear the radical )

3x = (- 3)³ = - 27 ( divide both sides by 3 )

x = - 9
