     If x=-6 and y=2, evaluate 2(y-3xy)

  First, We need to simplify the expression by multiplying the parentheses by 2:-

$\longmapsto\sf{2y-6xy}$

Now , Replace y with 2 and x with -6:-

$\longmapsto\sf{2(2)-6(-6)(2)}$

Simplifying,

$\longmapsto\sf{4-6(-12)}$

Further simplifying,

$\longmapsto\sf{4+72}$

Adding,

$\longmapsto\underline{\boxed{\sf{76}}}$

Good luck with your studies.
