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

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.
