2y-3y-\left(-4\right)+5y-6+10y=12y-12+36
To find the opposite of 3y-4, find the opposite of each term.
2y-3y+4+5y-6+10y=12y-12+36
The opposite of -4 is 4.
-y+4+5y-6+10y=12y-12+36
Combine 2y and -3y to get -y.
4y+4-6+10y=12y-12+36
Combine -y and 5y to get 4y.
4y-2+10y=12y-12+36
Subtract 6 from 4 to get -2.
14y-2=12y-12+36
Combine 4y and 10y to get 14y.
14y-2=12y+24
Add -12 and 36 to get 24.
14y-2-12y=24
Subtract 12y from both sides.
2y-2=24
Combine 14y and -12y to get 2y.
2y=24+2
Add 2 to both sides.
2y=26
Add 24 and 2 to get 26.
y=\frac{26}{2}
Divide both sides by 2.
y=13
Divide 26 by 2 to get 13.
