5y + -1 = y + 9
Reorder the terms:
-1 + 5y = y + 9
Reorder the terms:
-1 + 5y = 9 + y
Solving
-1 + 5y = 9 + y
Solving for variable 'y'.
Move all terms containing y to the left, all other terms to the right.
Add '-1y' to each side of the equation.
-1 + 5y + -1y = 9 + y + -1y
Combine like terms: 5y + -1y = 4y
-1 + 4y = 9 + y + -1y
Combine like terms: y + -1y = 0
-1 + 4y = 9 + 0
-1 + 4y = 9
Add '1' to each side of the equation.
-1 + 1 + 4y = 9 + 1
Combine like terms: -1 + 1 = 0
0 + 4y = 9 + 1
4y = 9 + 1
Combine like terms: 9 + 1 = 10
4y = 10
Divide each side by '4'.
y = 2.5

Y plus 7 equals 9?
Y+7=9 equals 2+7=9.
Y equals 10x - 9 y equals x plus 18?
(3,21)
Y equals 5x plus 18 y equals 2x plus 9?
5x+18 = 2x+9 5x-2x = 9-18 3x = -9 x = -3 and y = 3
What are the order pairs for x equals y plus 3 and 2x plus y equals -3?
The answer is - not are - (-6, 9).
What is 9 equals -23 plus y?
-14
Y plus 7 equals 9?
Y+7=9 equals 2+7=9.
X plus y equals 10 and y equals x plus 8?
(1, 9)
What does y equals 3x plus y and y equals x-9 equal?
y = 3x + y => x = 0then y = x - 9 => y = 0 - 9 = -9.

-14
X plus y plus z equals 9 and x plus 2y plus 3z equals 23 and x plus 5y-3Z equals -7 solve for x and y and z?
Can you help with this equation? Thanks. Solve for x and y and z for the following. x plus y plus z equals 9 x plus 2y plus 3z equals 23 x plus 5y plus -3z equals -7
For x plus y plus z equals 9 2x-y-z equals -6 and x plus y-z equals 1 what is the echelon matrix?
3x + 2 = 82
