You didnt specify what you wanted help with, but I assume you would like help simplifying it?
-2(-4x+5)+6x
According to BEDMAS (brackets, exponents, division, multiplication, addition, subtraction), we should first simplify the brackets bit "-2(-4x+5)"
-2(-4x+5)=(-2)*(-4x)+(-2)(5)=8x-10
Now we can add the 6x
So we get the final answer of
8x-10+6x=14x-10
