7y-6y = 1/2+1+3/3
y = 1/2+1+1
y = 1/2+2
y = 5/2 or 2.5

6y + 1/2 + 1 = 7y - 3/3 changes to 6y + 3/2= 7y - 1
*Eliminate fractions > multiply the denominator by everything >
2(6y) + 2(3/2)= 2(7y) - 2(1)
*Cancel "like" terms and combine the remaining terms >
2(6y) + 3= 2(7y) - 2(1)
12y + 3 = 14y - 2
First: combine "y" variables > subtract 14y from both sides (Opposite side means opposite sign) >
12y - 14y + 3 = 14y - 14y - 2
-2y + 3 = - 2
Sec: subtract 3 from both sides >
-2y + 3 - 3 = - 2 - 3
-2y = -5
Third: divide both sides by -2 >
-2y/-2 = -5/-2
y = 5/2
P.S. since 5/2 can't be simplified into lowest terms > it doesn't need to be changed into a decimal :-)

6y+1/2+1=7y-3/3
6y+(1/2) = 7y-1-1
1/2 = 7y-6y -2
1/2 = y-2
1/2 +2 = y
1/2 + 4/2 = y
y = 5/2 or 2.5
I hope this one helps. :)

1/2 + 3/3 = 7y-6y ( by transpose)
1/2+ 1 = y
1 1/2 =3/2 =y

6y= -1 1/2-3/3+7y
6y-7y= -2/2 +1/2 - 3/3 3/3=1
-1y=-2/2 +1/2 -2/2
-y=-4/2 +1/2
-y=-3/2
y=1 1/2
