 <span>3x + x - 13 + 4 - 6x =12  

Combine like terms....

- 2x - 9 =12 

Add 9  to both sides....

-2x = 21

Divide both sides by -2 to get x by its self....

x = -21/2</span>

mica and denise are reading the same novel. mica has read 1/2 of the novel, and denise has read 1/3 of the novel. how much more
vovangra [49]
You convert the fractions into 6ths. So 1/3. You would multiply both parts by 2 (top and bottom denominators) and that would be 2/6. 1/2 of 6 is 3/6. So the answer would be 1/6
