6y=4y+8
take away 4y from each side- have to keep it balanced
then it is 2y=8
divide each side by 2 to get one y
y=4
if you don't get it, ask me. my username is Confuzzled88

5x plus 4y equals 12 7x - 6y equals 40?
(4, -2)
What is y 10y plus 23 equals 4y plus 26?
y = ½ (6y = 3)
What is the solution set of the given equation 4y - 6y plus 9y equals -2?
4y - 6y + 9y = -2Combine like terms on the left side:7y = -2Divide each side by 7:y = -2/7The solution set is: { -2/7 }
3x -6y equals 9 5x plus 4y equals -27?
3x - 6y = 9, 5x + 4y = -27 6x - 12y = 18, 15x + 12y = -81 21x = -63 x = -3 (3 x -3) = 9 + 6y (-9 - 9)/6 = y y = -3 Check: (5 x -3) + (4 x -3) = -15 -12 = -27 QED
What are the solutions to the simultaneous equations of 3x plus 2y equals 5 and x plus 2y equals 7?
x = 7 - 2y 3x = 21 - 6y 21 - 6y + 2y = 5 21 - 4y = 5 21 - 16 = 5 4y = 16 y = 4 x + 8 = 7 x = -1 Check it. -3 + 8 = 5 -1 + 8 = 7 It checks.
What is x equals 4y-2 and x equals 6y plus 8?
By definition: 4y-2 = 6y+8 4y-6y = 8+2 -2y = 10 y = -5 and by substituting this value into the equation x = -22
-6y plus 14 plus 4y equals 32?
-6y + 14 + 4y = 32-2y = 32 - 14-2y = 18y = - 9
X plus 4y equals 11x-6y equals 11?
but crack
What is the answer to 6y equals 10 plus 4y?
6y 10+4y subtract 4y from each side 2y 10 divide both sides by 2 y = 5
5x plus 4y equals 12 7x - 6y equals 40?
(4, -2)
What is 6y equals 10 plus 4y?
6y = 10 + 4ySubtract 4y from each side:2y = 10Divide each side by 2:y = 5
What is y 10y plus 23 equals 4y plus 26?
y = ½ (6y = 3)
4y-4 plus y plus 24 equals 6y plus 20-4Y equals Need to show process?
Algebra4y-4 plus y plus 24 equals 6y plus 20-4YCombine like terms5y+20=2y+20Isolate Y3y=0y=0
3y-7 plus y plus 27 equals 6y plus 20-4y?
3y - 7 + y + 27 = 6y + 20 - 4y Collect terms: 4y + 20 = 2y + 20 Subtract 20 4y = 2y The only way that can happen is if y = 0
What is the answer to 26 equals -6y plus 6 plus 2y?
26 = -6y + 6 + 2y = -4y + 6 Subtracting 6 from both sides: 20 = -4y Dividing both sides by (-4): -5 = y
What is the graph of 6x-6y equals -48 and -10x plus 4y equals 92?
Two straight lines that intersect.
What is 10y equals 2y-6y plus 7?
10y = 2y - 6y + 7 10y =-4y + 7 10y +4y = 7 14y = 7 y = 1/2 = .5
