Y² + 12x - 6y + 21 = 0
<u> - 21 - 21</u>
y² + 12x - 6y = -21
12x + y² - 6y = -21
12x + (y² - 6y + 9) = -21 + 9
<u>12x</u> + <u>(y - 3)²</u> = <u>-12</u>
-12 -12 -12
-x + <u>(y - 3)²</u> = 1
-12

X + 2x = 5 + 10
<span>Simplifying
x + 2x = 5 + 10
Combine like terms: x + 2x = 3x
3x = 5 + 10
Combine like terms: 5 + 10 = 15
3x = 15
Solving
3x = 15
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
