Answer 3

you want to know for what value of x, the function spits out 3

Answer 4

so set the function equal to 3 and solve x

Answer 5

\[\large 3 = \dfrac{2x+3}{5}\]

solve \(x\)

Answer 6

so x = 6

Answer 7

Yep!

Answer 8

is this right?
f(1) when f(x) = 5x + 1
f(x) = 5(1) + 1
x = 6

Answer 9

right!

Answer 10

and last part of the question
3y - 7 = y + 5
-5 - 5
