If 5-3(2a+1)=-4+10, what is the value of a+2

givi [52]

$\\ \rm\Rrightarrow 5-3(2a+1)=-4+10$

$\\ \rm\Rrightarrow 5-6a-3=6$

$\\ \rm\Rrightarrow -6a+2=6$

$\\ \rm\Rrightarrow -6a=6-2$

$\\ \rm\Rrightarrow -6a=4$

$\\ \rm\Rrightarrow a=\dfrac{4}{-6}$

$\\ \rm\Rrightarrow a=\dfrac{2}{-3}$

Now

$\\ \rm\Rrightarrow a+2$

$\\ \rm\Rrightarrow \dfrac{2}{-3}+2$

$\\ \rm\Rrightarrow \dfrac{2-6}{-3}$

$\\ \rm\Rrightarrow \dfrac{-4}{-3}$

$\\ \rm\Rrightarrow \dfrac{4}{3}$
