Answer:
W=-71/36=-1.972
Explanation:
Isolate w on one side of the equation.
12(3w+8)=25
12(3w+8)/12=25/12 (First, divide by 12 from both sides.)
25/12 (Solve.)
3w+8=25/12
3w+8-8=25/12-8 (Subtract 8 from both sides.)
25/12-8 (Solve.)
25/12-8=-71/12
3w/3=-71/12/3 (Then, divide by 3 from both sides.)
-71/12/3 (Solve.)
-71/12/3=-1.972
w=-71/12=-1.972
As a result, the correct answer is w=-71/12=-1.972.
