Question 211493
x-{3x-[2x-(8-x)+2]+3}-6=0 ... Start with the given equation.



x-{3x-[2x-8+x+2]+3}-6=0 ... Distribute the inner most parenthesis



x-{3x-[3x-6]+3}-6=0 ... Combine like terms.



x-{3x-3x+6+3}-6=0 ... Distribute



x-9-6=0 ... Combine like terms.



x-15=0 ... Combine like terms again



x=15 ... Add 15 to both sides.



So the answer is {{{x=15}}}
