Two ways to see this: 6y=8-9+6y 6y=6y-1 No answer here 6y= 8-(9+6y) 6y+(9+6y)=8 12y+9=8 12y=-1 y= -(1/12) or -0.08333...
7y-8 = 6y+1 7y-6y = 1+8 y = 9
(2y + 3)(4y^2 - 6y + 9)
It does nothing! 4x + 6y = 24 7x + 6y = 9 Subtracting the first equation from the second gives: 3x = - 15 so that x = -5 Substituting the value of x in the first equation gives -20 + 6y = 24 so that 6y = 44 and so y = 22/3 or 71/3
It's 0

7y-8 = 6y+1 7y-6y = 1+8 y = 9
This simplifies to 6+13y If you meant 9+7y-(3+6y) then it becomes 6+y It is not clear from the problem which you meant.
-9x+6y = 54 6y = 9x+54 y = 1.5x+9 slope = 1.5
-6y + 14 + 4y = 32-2y = 32 - 14-2y = 18y = - 9
(2y + 3)(4y^2 - 6y + 9)
It does nothing! 4x + 6y = 24 7x + 6y = 9 Subtracting the first equation from the second gives: 3x = - 15 so that x = -5 Substituting the value of x in the first equation gives -20 + 6y = 24 so that 6y = 44 and so y = 22/3 or 71/3
It is 3(2y+3) when factorized
-6y - 9 = 5y + 24Add 6y to each side of the equation:-9 = 11y + 24Subtract 24 from each side:-33 = 11yDivide each side by 11:-3 = y
(2y + 3)(4y2 - 6y +9)
It's 0
No solution. Multiply second equation by 3 and get 12x + 6y = 0 but already stated 12x + 6y = 9...
