Question

5/6d-5/9d=1/2d+1/3

5/6a-4/5a+1=1/2a-2/5

y-2/8=3y-4/3

d-1/11=2d-3/8

n+4/6=3n-2/7

СРОЧНО!!!

Answer 1

5/6d-5/9d-1/2d=1/3
-2/9d=1/3
-d=3/2=1 1/2
d=-1 1/2

5/6a-4/5a-1/2a=-2/5-1
-7/15a=-7/5
a=3

у-3у=2/8-4/3
-2у=-13/12
у=13/24

d-2d=1/11-3/8
-d=-25/88
d=25/88

n-3n=-2/7-4/6
-2n=-20/21
n=10/21
