Answer 2

8x+x-3+2(x+1)=16x+4(5-3x)
8x+x-3+2x+2=16x+20-12x
11x-1=4x+20
11x-4x=20+1
7x=21
x=3

Answer 3

It seems like there might be a typo or a missing part in the equation you provided. The equation "X++ = 2x +" is not complete and doesn't make sense as it stands. An equation should have an equal sign (=) to indicate that the expression on the left side is equal to the expression on the right side.

If you intended to write a complete equation, please provide the missing or corrected part, and I'll be happy to help you with the math or solve for the variable you're interested in.
