You wanna get the y by itself. So you will subtract 11.9 then move it to the other side. so that is 10.5y = -11.9x +178.5. Then divide everything by 10.5. Then you get y = -11.9x/10.5+17. 11.9x/10.5 is because you cant put 10.5 into 11.9 evenly so you leave it as a division problem.

Let's solve for x.
11.9x+10.5y=178.5 

Step 1: Add -10.5y to both sides.
11.9x+10.5y+−10.5y=178.5+−10.5y
11.9x=−10.5y+178.5

Step 2: Divide both sides by 11.9.

11.9x/11.9=−10.5y+178.51/1.9
x=−0.882353y+15
