w= 31.4
Step 1: 4*Pi = 12.566370614359
Step 2: -6*Pi = -18.849555921539
Step 3: Rewrite equation (12.566370614359=w-18.849555921539)
Step 4: Move the number that is equivalent to 6Pi over to the other side of the equal sign to get the variable alone. (12.566370614359+18.849555921539 = 31.415926535898 ) The problem should now look like this, 31.415926535898=w
Step 5: Divide the numbers (which you don't really need to do here since the "number" in front of w is 1. This is helpful to know for future problems though.)
Step 6: Round to the nearest tenths place (or however you need to) giving you the final answer of 31.4
