Answer:
please, check the explanation.
Step-by-step explanation:
Hello, I can help you with this
using the graph of a function you can find the value of f (x), all you need to do is locate on the x axis, the value, in this case 3, and we will find f (3), locate the number (3 ) on the x-axis and see what is the value of y that the function takes at that point, that will be the value f (3)
I hope it helps , Have a nice day

Let "x" be the "unknown number" for which we are to solve.
8x − (-54/9) = -18 ; Solve for "x" ;
→ 8x − (-6) = - 18 ;
→ 8x + 6 = - 18 ;
Subtract "6" from each side of the equation:
→ 8x + 6 − 6 = - 18 <span>− 6 ;
to get: 8x = -24 ;
Divide EACH SIDE of the equation by "8" ; to isolate "x" on one side of the equation ; & to solve for "x" ;
8x / 8 = -24 / 8 ;
to get: x = -3 .

The number is: " -3 " .

Answer:
or 
(Not sure which one is preferred in your case)
Step-by-step explanation:
<u>Key skills needed: Evaluating expressions</u>
1) We are given: 
2) To solve for the x variable, we want to leave the term with "x" by itself.
This means we add 10 to both sides
--> 
(Since -10 and +10 cancel out to make 0 or nothing)
3) Then we divide by 5 on both sides to get "x" completely by itself.
-----> 
4) You can keep it as is so --> 
or you can divide "y" by 5 and "10" by 5 and get --> 
(I am not sure which form is preferred one is preferred as the teacher matters)
