Simplifying
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
Simplifying
y = 2.5
Y+7=9 equals 2+7=9.
(3,21)
5x+18 = 2x+9 5x-2x = 9-18 3x = -9 x = -3 and y = 3
The answer is - not are - (-6, 9).
-14
Y+7=9 equals 2+7=9.
(1, 9)
y = 3x + y => x = 0then y = x - 9 => y = 0 - 9 = -9.
(3,21)
y = -2/5
5x+18 = 2x+9 5x-2x = 9-18 3x = -9 x = -3 and y = 3
The answer is - not are - (-6, 9).

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
3x + 2 = 82
