i totally forgot how to solve this
When the number w is multiplied by 4, the result is the same as when 4 is added to w. What is the value of 3w?

4w =w+4
subtract a w from each side
3w=4
now, that was easy :)

The question translates from "English" into "mathematics" like this:
When 4w = 4 + w, what is 3w?
From there, you solve for "w" with the first equation, like this:
4w = 4 + w
4w - w = 4
3w = 4
Thus, you don't even have to solve all the way for "w" because the problem solving gives you the answer to the second part, which is what is 3w? It's "4".
Hope it helps!

the number w is multiplied by 4:
4w
the result is the same as when 4 is added to w:
4 + w
4w = w + 4
3w = 4
w = 4/3
3(4/3) = 4
so the value of 3w is 4

Hey there!
Here's the answer.
4w=w+4 --> Write the problem.
3w=4 Subtract w on both sides of the equation.
So the value of 3w is 4.
Hope it helps!

4W= W+4
SUBTRACT W FROM BOTH SIDES
3W=4
SIMPLIFY
W=4/3
WHAT IS 3 W?
3W=3(4/3)
3W=4

4w = 4+ w
3W = 4
W = 4/3 = 1.33333333333333333333....
