An example of a two-step equation with m = -2 can be:
2(m + 5) = 6
2.
We substitute x,
3/4 (4/3) + 1/2 = 3/2
1 + 1/2 = 3/2
3/2 = 3/2
Thus, this is a solution to the equation.
Using the inverse function, it is found that the equation is:

It's initial value is 20.
---------------------------
We want to find the inverse of:

To do this, we <u>exchange y and t, and isolate y.</u>
Then:








It's initial value is:

Rounding, 20.

Kent can paint the room 1/5
luannda can paint the room 1/3
(3+5) (5*3) = 8/15 or 0.53 th of the room together but just for kent would be 1/5
The equation is given as W varies directly with u and inversely with d, then the equation is written as:
W = k1u
here k2 is the proportionality constant.
and p = k2

here k2 is the proportionality constant.
Thus, combining both equations we get, p = K

where K = K1*K2, is the proportionality constant.
