Alright so, let’s break this down.

To find the first coordinate you need to solve the first equation

To do that you can do
6+9=15
So that mean 3x has to be equal to 15
You divide 15 by 3

The answer to that is the solution to the first equation, or the first coordinate.

For the second one, you know x has to be negative because the solution is negative

2x is going to have to equal -20
-20/2 gets you the solution

Remember that it will be negative
You now have both of the coordinates

You take coordinate A and technically add coordinate B to it
You do that because B is negative and A is positive
Then you have the answer to c

\bf \begin{cases}
f(x)=\sqrt[3]{7x-2}\\\\
g(x)=\cfrac{x^3+2}{7}
\end{cases}\\\\
-----------------------------\\\\
now
\\\\
f[\ g(x)\ ]\implies f\left[ \frac{x^3+2}{7} \right]\implies \sqrt[3]{7\left[ \frac{x^3+2}{7} \right]-2}\implies \sqrt[3]{x^3+2-2}
\\\\\\
\sqrt[3]{x^3}\implies x\\\\
-----------------------------\\\\
or
\\\\
g[\ f(x)\ ]\implies g\left[\sqrt[3]{7x-2}\right]\implies \cfrac{\left[\sqrt[3]{7x-2}\right]^3+2}{7}
\\\\\\
\cfrac{7x-2+2}{7}\implies \cfrac{7x}{7}\implies x

thus f[ g(x) ] = x indeed, or g[ f(x) ] =x, thus they're indeed inverse of each other

a = 3

XY = 3a - 4

= 3×3 - 4
