To simplify expressions with nested parenthesis, start at the innermost expression.
Remove the parenthesis inside the bracket. To do so, distribute 5 to x+y and -2 to 3x-4y.
Combine like terms.
And distribute 2 to 13y-x.
`=26y - 2x`
Hence, `2[5(x+y)-2(3x-4y)]=26y-2x` .
To simplify, remove the parenthesis by distributing -3 to x-2y.
And, combine like terms.
Hence, `6x-3(x-2y)=3x+6y` .
