Solve ax + by = −c for x.

x equals the quantity negative b times y minus c all over a
x equals the quantity negative b times y plus c all over a
x equals the quantity b times y plus c all over a
x equals the quantity b times y minus c all over a

  x equals the quantity negative B times y minus C all over A

Step-by-step explanation:

Subtract By and divide by A:

  Ax + By = -C . . . . starting equation

  Ax = -By -C . . . . . subtract By from both sides

  x = (-By -C)/A . . . . divide both sides by A

step-by-step explanation:

x^2 -12x + 36 + y^2 = 36

x^2 + y^2 = 12x

r^2 = 12rcos(theta)

r = 12 cos(theta)

24
