What is the value of n in the equation - (2n + 4) + 6 = - 9 + 4 (2n + 1) ?

- (2n+4) + 6=-9+4 (2n+1) perform indicated multiplications ...

-2n-4+6=-9+8n+4 combine like terms on both sides ...

-2n+2=8n-5 subtract 2 from both sides

-2n=8n-7 subtract 8n from both sides

-10n=-7 divide both sides by - 10

n=7/10

n=0.7
