Solve for n.
2/3(1+n)=-1/2n

Basically what you do is that you first distribute 2/3 into 1 and n. So you’ll get 2/3+2/3n=-1/2n then you’ll multiply BOTH sides by 6 to eliminate the fractions because no one likes fractions. You’ll get 4+4n=-3n so then you’ll subtract 4 on BOTH sides and then you divide. And get n= -4/7 I hope this helps!!!
