w=−8

Step-by-step explanation

Let's solve your equation step-by-step.

39−12w=7−16w

Step 1: Simplify both sides of the equation.

39−12w=7−16w

39+−12w=7+−16w

−12w+39=−16w+7

Step 2: Add 16w to both sides.

−12w+39+16w=−16w+7+16w

4w+39=7

Step 3: Subtract 39 from both sides.

4w+39−39=7−39

−12w+39=−16w+7

Step 2: Add 16w to both sides.

−12w+39+16w=−16w+7+16w

4w+39=7

Step 3: Subtract 39 from both sides.

4w+39−39=7−39
