0.6y-1=0.15\left(2y+3\right)-0.85
Use the distributive property to multiply 0.2 by 3y-5.
0.6y-1=0.3y+0.45-0.85
Use the distributive property to multiply 0.15 by 2y+3.
0.6y-1=0.3y-0.4
Subtract 0.85 from 0.45 to get -0.4.
0.6y-1-0.3y=-0.4
Subtract 0.3y from both sides.
0.3y-1=-0.4
Combine 0.6y and -0.3y to get 0.3y.
0.3y=-0.4+1
Add 1 to both sides.
0.3y=0.6
Add -0.4 and 1 to get 0.6.
y=\frac{0.6}{0.3}
Divide both sides by 0.3.
y=\frac{6}{3}
Expand \frac{0.6}{0.3} by multiplying both numerator and the denominator by 10.
y=2
Divide 6 by 3 to get 2.
