3\left(2y+5\right)+4y=2\left(3.5+y\right)
Multiply both sides of the equation by 24, the least common multiple of 8,6,12.
6y+15+4y=2\left(3.5+y\right)
Use the distributive property to multiply 3 by 2y+5.
10y+15=2\left(3.5+y\right)
Combine 6y and 4y to get 10y.
10y+15=7+2y
Use the distributive property to multiply 2 by 3.5+y.
10y+15-2y=7
Subtract 2y from both sides.
8y+15=7
Combine 10y and -2y to get 8y.
8y=7-15
Subtract 15 from both sides.
8y=-8
Subtract 15 from 7 to get -8.
y=\frac{-8}{8}
Divide both sides by 8.
y=-1
Divide -8 by 8 to get -1.
