2a-(8a+1)-(a+2)*5=9
Sorry I forgot the 5 and an a (Thank you Alan!)
\(2a-(8a+1)-(a+2)\times5=9 \)
\(2a-8a-1-5a-10=9\)
\(-11a=9+10+1-2\)
\(-11a=18\)
\({\color{blue}a=-\frac{18}{11}}\) !
\({\color{blue}a=-1\frac{7}{11}}\) !
\(2a-(8a+1)-(a+2)=9 \)
\(2-8a-1-a-2=9\)
\(-9a=9+2+1-2\)
\(-9a=10\)
\({\color{blue}a=-\frac{10}{9}}\) !
\({\color{blue}a=-1\frac{1}{9}}\) !
Sorry I forgot the 5.
\(2-8a-1-5a-10=9\)
\(-13a=9+10+1-2\)
\(-13a=18\)
\({\color{blue}a=-\frac{18}{13}}\) !
\({\color{blue}a=-1\frac{5}{13}}\) !
Thank you Alan! I will be more exact in the future!
\(-11a=9+10+1\)
\(-11a=20\)
\({\color{blue}a=-\frac{20}{11}}\) !
\({\color{blue}a=-1\frac{9}{11}}\) asinus :- ) !
