Question

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

Answer 1

Answer:

w = -4

Step-by-step explanation:

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

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

Hope this helps.

Answer 2

Answer:

$w=-4$

Step-by-step 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!
