Answer:

y = -21/2

Explanation:

multiply both sides of the equation by 21 so it would be

7y+42=3y

move the terms

7y-3y=-42

collect like terms

4y=-42

divide both sides by four

y= -21/2

Answer:

y=2

y=0

Explanation:

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

7*y-1-(3*y^2+y-1)=0

(7y - 1) - ((3y2 + y) - 1) = 0 3.1 Pull out like factors :

6y - 3y2 = -3y • (y - 2)
