6y2 - 36 = 6y
Subtract 6y from each side:
6y2 - 6y - 36 = 0
Divide each side by 6:
y2 - y - 6 = 0
Factor the expression on the left side:
(y + 2) (y - 3) = 0
The equation is a true statement if either factor is = 0.
y + 2 = 0 ==> y = -2
y - 3 = 0 ==> y = 3

How do you solve -12x equals 6y?
its just a line, there are many answers that would work -12x-6y=0 -12x=6y x=-y/2 y=-2x
How do you solve for y in 5x-6y equals 13?
Watch closely:5x - 6y = 13Subtract 5x from each side of the equation:-6y = 13 - 5xDivide each side by -6 :y = 5x/6 - 13/6
-6y plus 5 equals -67?
-6y + 5 = -67y=12-6y = -72-y = -12y = 12
-6y plus 3 equals -7y plus 8?
-6y+3 = -7y+8 -6y+7y = 8-3 y = 5
What is the slope of -9x plus 6y equals 54?
-9x+6y = 54 6y = 9x+54 y = 1.5x+9 slope = 1.5
How do you solve 6y-5 equals -5?
6y - 5 = -5; so 6y = -5 + 5; so 6y = 0; so y = 0
Solve 7x 6y equals 126?
Not sure if you mean 7x 6y as in 7*6y=126, where * means "multiplied by" and you must solve for y or if you mean that we must solve for both x and y, but the answer to the part where you are solving 7*6y=126 is 3.
What is the solution of x equals 6y-4 and x equals -2y plus 28 using substitution?
x=6y-4x=-2y+28Substitute (6y-4) for x in the second equation and solve for y:6y-4=-2y+288y=32y=4Then solve for x:x=6(4)-4=20(20,4)
How do you solve -12x equals 6y?
its just a line, there are many answers that would work -12x-6y=0 -12x=6y x=-y/2 y=-2x
What is 6y equals 5y plus 2y?
6y equals 5y plus 2y can be simplified to 6y = 7y. To solve for y, subtract 7y from both sides of the equation, which gives 6y - 7y = 0. This simplifies to -y = 0, or y = 0.
Solve the equation10y equals 6y plus 5 plus 3y?
10y= 6y+5+3y 10y=6+9y y=6
Solve this system of equation using substitution 2x plus 6y equals 24 and 3x-2x equals 24?
Solve this system of equation using substitution 2x plus 6y equals 24 and 3x-2x equals 24 ?Improved Answer:2x+6y = 243x-2x = 24 => x =24Substitute the value of x into the top equation to find the value of y:48+6y = 246y = 24-486y = -24y = -4So: x = 24 and y = -4
Solve by the elimination method x plus 6y equals 19 -x plus 6y equals 17?
(A) x + 6y = 19 (B) -x + 6y = 17 (A)+(B): 12y = 36 so that y = 3 Substituting this value of y in (A), x + 18 = 19 so x = 1.
Solve for y -3x plus 6y equals 12?
y-3x+6y=12 7y=3x+12 y=3x/7 +12/7
Solve the system of equations 3x - 6y equals 30 y equals -6x plus 34?
x = 6 and y = -2
How do you solve 55 equals 6y?
You write: --> divide both sides by 6 --> cross out the 6's --> here's y! :) 55 = 6y --> 55/6 = 6y/6 --> 55/6 = y --> 9.16667 = y
How do you solve for y in 5x-6y equals 13?
Watch closely:5x - 6y = 13Subtract 5x from each side of the equation:-6y = 13 - 5xDivide each side by -6 :y = 5x/6 - 13/6
