You have a jar of marbles in front of you with the following colors: 7 - red, 12 - blue, 6 -
yellow and 9 - white. What are the odds of
selecting marble that is not blue, replacing it
and then one that is blue?

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116

a)(x-2)^2+(y-1)^2=9
