Question

-79 = 7w + 3(4w - 1) Show Work

Answer 1

w = -4

Explanation:

-79 = 7w + 3(4w - 1)

`-79 = 7w + 3(4w - 1)\\\\-79=7w+12w-3\\\\-79=19w-3\\\\-79+3=19w-3+3\\\\-76=19w\\\\(-76=19w)/(19)\\\\ -4=w\\\\\boxed{w=-4}`

Hope this helps.

Answer 2

`w=-4`

Explanation:

So we have the equation:

`-79=7w+3(4w-1)`

Distribute the right:

`-79=7w+12w-3`

Combine like terms:

`-79=19w-3`

Add 3 to both sides:

`-76=19w`

Divide both sides by 19:

`w=-4`

So, the value of w is -4.

And we're done!
