Solve -5 + w divided by 3 = -1.<br><br> 12<br> -12 <br> 2 <br> -2
son4ous [18]

Hello!

<u><em>Answer:</em></u>

<u><em>w=12</em></u>

<u><em>*The answer must have a positive sign.*</em></u>

Step-by-step explanation:

First, you add by 5 from both sides of an equation.

-5+\frac{w}{3}+5=-1+5

Then, you simplify.

\frac{w}{3}=4

Next, you multiply by 3 from both sides of an equation.

\frac{3w}{3}=4*3

And finally, simplify and solve. You can also multiply by the numbers from left too right.

4*3=12

Final answer: → w=12

Hope this helps!

Thanks!

-Charlie

Have a great day!

:)
