Hi there!
To make the subject of w = 3t + 11 t, we need to have t equal to something.
We can do this by first
moving t to one side by subtracting 3t from both sides:
w - 3t = 11
moving w to the other side by subtracting w from both sides of the equation:
-3t = 11 - w
dividing both sides of the equation by 3 to isolate t:
-t = (11 - w) ÷ 3
and turning t into a positive by multiplying the equation by -1.
t = (-11 + w) ÷ 3
That's the answer.
Hope this helps!
