Find the values of y: 3y^3(y^2+ 2/3y)=0

Long division setup showing an incomplete calculation. 12 is in the divisor, 6839 is in the dividend, and 5 hundreds and 6 tens is written in the quotient. 6000 is subtracted from 6839 to give 839. an unknown value represented by a box is being subtracted from 839. what number should be placed in the box to complete the division calculation?

What is the solution to the system of equations? y=1.5-3 y=-x
