For this case we must clear x from the given equation:

We passed 23 subtracting the other side of equality:

By definition,
is written as 
So, we have:

So, the solution of
for x is:

Answer:



To find the inverse of a function, replace x and y in the equation and solve for y. In our case...
x=2y-10
x+10=2y
y=x/2+5
Are there any opinions? i need to know to help you out, theres not much to go by:(
If you would like to simplify Q + S - T, you can
do this using the following steps:<span>
Q = 7m + 3n,
R = 11 - 2m,
S = n + 5,
T = -m - 3n + 8
</span>Q + S - T = 7m + 3n + n + 5 - (-m - 3n + 8) = 7m + 3n + n + 5 + m + 3n - 8 = 8m + 7n - 3
The correct result would be <span>8m + 7n - 3.</span>
