SOMEONE THAT KNOWS PRE CALCULUS I NEED HELP ON THESE QUESTIONS (Please don't leave stupid answers to take my points this is my third time asking for help on these and everyone just takes my points so please)

Step-by-step explanation:

answers= 12/5, 5/13, -13/12, 13/5, -12/13

Hope this was right, this is how my professor explained it at my school so tell me if I am wrong :)

-22

times both sides by 2, times () by 8, add alile terms, move terms, add alike and caculate divide both sides by 3

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
