If 8x^3 + 27y^3 = 730 and 3x^2y + 3xy^2 = 15 then evaluate 2x + 3y pls me

Given that, " and "

Using this two equations evaluate :

Using Cube formula for a+b,

Plug in a=2x \,\, \, and\, \, \, b=3y in the formula,

We know that the value of

Plug in this value in the above equation,

Now take 18 as common for the second and third term in the right hand side,

Now plug in the value 2x^2y+3xy^2\: \: as \: \: 15,

Taking Cube root on both sides, we get
