cubing both sides
(x+5y)cube=1000
xcube+125y cube+3x.5y(x+5y)=1000
x cube+125y cube+15xy×10=1000
x cube+125y cube+150xy-1000=0
(x+5y)cube=1000
xcube+125y cube+3x.5y(x+5y)=1000
x cube+125y cube+15xy×10=1000
x cube+125y cube+150xy-1000=0

Given Equation is x + 5y = 10.
On cubing both sides, we get
= > (x + 5y)^3 = (10)^3
= > x^3 + (5y)^3 + 3(x)(5y)(x + 5y) = 1000
= > x^3 + 125y^3 + 15xy(10) = 1000
= > x^3 + 125y^3 + 150xy = 1000
= > x^3 + 125y^3 + 150xy - 1000 = 0.
Hope this helps!
