Answer:
w=-11/4 or -2 and 3/4
Step-by-step explanation:
To solve this, we first have to cancel out the dividing by-3. We can use the inverse operation of division, which is multiplication. We have to multiply both sides by -3, and the equation becomes 4w+5= -6. Then, we subtract 5 from both sides. We get 4w= -11. We finally divide 4 on both sides, getting w=-11/4. -11/4 is in improper fraction form and -2 and 3/4 is in mixed number form.
