You have two terms with the variable, 7y and 12y. Move the variable with the smaller coefficient, which is 7y. To do this you have to look at the sign in front of the variable you're moving. Since there is no sign, you know it is +.
To move this variable you do the opposite, so you'll subtract 7y from both sides.
7y-74+44=12y-7y+11
This gives you 44=5y+11. You can turn it around to 5y+11=44 if it's easier.
Subtract 11 from both sides:
5y+11-11=44-11
5y=33
Divide both sides by 5.
y= 6.6 or 6 3/5

You first need to put the like terms together and it will be straight on from there, that is...
44-11=12y-7y
33=5y
(divide both sides by 5 to get y)
33/5=y then y=6.6

Step 1
7y + 44 = 12y +11
-7y -7y
Step 2
44 = 5y +11
-11 -11
Step 3
33=5y
/5 /5
Step 4
33/5=y or y=33/5

7y + 44 = 12y + 11
minus 7y from both sides
44 = 5y + 11
minus 11 from both sides
33 = 5y
divide both sides by 5
y = 33/5 = 6.6

7y+44=12y+11
-12y -12y
-5y+44=11
-44 -44
-5y=-33
(divide -33 by -5)
y=6.6

7y+44=12y+11
=7y-12y=11-44
=-5y=-33
divide both sides by -5
y=33/5
or in decimal
y=6.6 :)
