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.
