What does 4x plus 6y equals 24 7x plus 6y equals 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 equals 8-9 plus 6y Find the value of y?
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...
What is the answer to 7y-8 equals 6y plus 1?
7y-8 = 6y+1 7y-6y = 1+8 y = 9
2x plus 6y equals 24 and 5x - 2y equals 9?
(3, 3)
What is the answer to this matrix in arbitrary form- 3x 6y-z equals 9 and x plus y plus 3z equals 4?
It is a singular matrix.

What is the answer to 7y-8 equals 6y plus 1?
7y-8 = 6y+1 7y-6y = 1+8 y = 9
2x plus 6y equals 24 and 5x - 2y equals 9?

What is the slope of -9x plus 6y equals 54?
-9x+6y = 54 6y = 9x+54 y = 1.5x+9 slope = 1.5
-6y plus 14 plus 4y equals 32?
-6y + 14 + 4y = 32-2y = 32 - 14-2y = 18y = - 9
What is the order pair for 2x plus 6y equals 24 and 5x - 2y equals 9?
(3,3)
What is the answer to this matrix in arbitrary form- 3x 6y-z equals 9 and x plus y plus 3z equals 4?
It is a singular matrix.
What is the solution of the following linear system 12x plus 6y equals 9 4x plus 2y equals 0?
No solution. Multiply second equation by 3 and get 12x + 6y = 0 but already stated 12x + 6y = 9...
What is y if -6y - 9 equals 5y plus 24?
-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
What is the sum of this equation -5x plus y equals -12 -3x plus 6y equals -12?
-5x + y = -12- 3x + 6y = -12Since both of expressions have a value of -12, their sum is - 24. This is true only whenx = 20/9 and y = -8/9.-5x + y = -12y = 5x - 12- 3x + 6y = -12-3x + 6(5x - 12) = -12-3x + 30x - 72 = -1227x = 60x = 60/27x = 20/9y = 5x - 12y = 5(20/9) - 12y = 100/9 - 12y = (100 - 108)/9y = -8/9
5x plus 9y equals 0 6x plus 6y equals 2?
5x + 9y = 06x + 6y = 2 use substitution method5x + 9y = 0y = -5x/96x + 6y = 2 substitute y with -5x/96x + 6(-5x/9) = 26x - 30x/9 = 2 multiply by 9 to both sides54x - 30x = 1824x = 18x = 24/18 = 4/3y = -5x/9 = (-5/9)x substitute x with 4/3y = (-5/9)(4/3) = -20/27Thus the solution is x = 4/3 and y = -20/27.
