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.
3x + 6y + 6x = 9x + 6y which can be factorised as 3(3x +2y)
Y = 1.125 2Y + 6Y - 9 = 0 2Y + 6Y = 9 Y(2+6) = 9 8Y = 9 Y = 9/8 = 1 1/8 = 1.125 PROOF: 2(1.125) + 6(1.125) - 9 = 0 2.5 + 7.5 - 9 = 0 9 - 9 = 0
6x + 3y + 6y - 2x = (6x - 2x) + (3y + 6y) = 4x + 9y
That is the answer. If y is undefined, then 1+6y is as far as you can go.
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...
k(7k + 9)
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
-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...
