Y = 5x - 10
Can you solve for x

    or           (Not sure which one is preferred in your case)

Step-by-step explanation:

Key skills needed: Evaluating expressions

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)

Hope you understood and have a nice day!!

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

answer:

f(5/2) = 10/3
