Please note that if we use the elimination method for solving your system, we have to solve the subsequent equation:

9x+2=-3x+12

then grouping similar terms, we get:

12x=10, or dividing both sides by 12:

x=10/12=5/6

Next step I substitute x=5/6 into your first equation, namely:

y=9*(5/6)+2=3*(5/2)+2=(15/2)+2=19/2=9 1/2

so your solution is:

(5/6, 9  1/2) , namely option (a)
