We can start by saying that 4/3w+ 3/3w = 133.
we can simplify to 7/3w = 133.
multiply both sides by 3 to get 7w = 399.
divide both sides by 7 to get 57.

What do you need help with?
The standard form of a quadratic equation is
,
where
,
, and
are coefficients. You want to get the given equation into this form. You can accomplish this by putting all the non-zero values on the left side on the equation.
In this case, the given equation is

Since
is on the right side of the equation, we subtract that from both sides. The resulting equation is

Looking at the standard form equation
, we can see that
