There are 3 *methods* ** to solve it. I am using substitution method.**

Explanation:

This is how we do this:
x=(-9y-5)/2x=9y52 ( From equation 1)
putting the value of xx in equation 2
6(-9y-5)/2 - 12= -3y69y5212=3y

-27y-15-12=-3y27y1512=3y

-27 = 24y27=24y

y= -27/24y=2724
therefore y=-9/8

Now put the value of 'y'in the first equation to get the value of 'x'
Hence solved.
