The 'answer' is the number that 'y' must be if the statement is true.
5 + 7y = 11 + 9y
Subtract 7y from each side of the equation:
5 = 11 + 2y
Subtract 11 from each side:
-6 = 2y
Divide each side by 2 :
-3 = y

What is 5x-9y equals 7 7y-3x equals -5?
If: 5x-9y = 7 and 7y-3x = -5 Then: x = 1/2 or 0.5 and y = -1/2 or -0.5
What is x-7y plus 4x-2y simplified?
Splitting the equation up into the two variables: x + 4x = 5x -7y + -2y = -9y Therefore, the simplified version is: 5x - 9y
What is 9y-11 equals 7?
9y-11=7 +11 +11 9y=18 y=2
6x - 6y plus 11 equals 17 9y equals 3x plus 15 Solve the system of equations and enter the solution as an ordered pair?

What does y equal if 9y plus 4.8 equals 17.4?
9y = 12.6 y = 1.4
10y equals 2y plus 4 plus 7y?
10y = 9y + 4, so y = 4
What is 5x-9y equals 7 7y-3x equals -5?
If: 5x-9y = 7 and 7y-3x = -5 Then: x = 1/2 or 0.5 and y = -1/2 or -0.5
-9y plus 8 equals -91?
-9y + 8 = -91-9y = -91 -8-9y = -99y = -99-----9y = 11-99/-9 = 11 because -9X11 = -99
Simplify 3x - 2y plus 9 plus 9y - x?
3x-2y+9+9y-x = 2x+7y+9
Factor 6xsquare plus 13xy - 63ysquare?
(3x - 7y)(2x + 9y)
Solve 4r plus 6 equals 14?
9y subtract 11 equals 7
What is x-7y plus 4x-2y simplified?
Splitting the equation up into the two variables: x + 4x = 5x -7y + -2y = -9y Therefore, the simplified version is: 5x - 9y
What is 9y-11 equals 7?
9y-11=7 +11 +11 9y=18 y=2
Y-8x plus 9y equals?
Y-8x plus 9y equals 10y-8x.
If 3x equals 7y-2 and 9y equals 4x plus 1 Then what is the value of x and y?
3x = 7y - 2 (subtract 3x and 7y to both sides of the first equation)9y = 4x + 1-7y = -3x - 2 (multiply by 4 each term of both sides of the first equation)9y = 4x + 1 (multiply by 3 each term of both sides of the second equation)-28y = -12x - 827y = 12x + 3 (add both equations)-y = -5 (multiply by -1 both sides)y = 53x = 7y - 2 (substitute 5 for y)3x = 7(5) - 23x = 33 (divide both sides by 3)x = 11Thus, the solution of the given system of the equations is x = 11 and y = 5.
How do you write 7y 2y in its simplest form?
