so I'm given the problem. if (x, 22) is a solution for the function (x) = 3x - 5, what is x?

okay so how do i do this. I'm completely lost. please help!

f(x) = 3x - 5

( x, y)

x is unknown here, but y is 22. y is the output of the function 3x - 5

so y = 3x - 5

Since we know y = 22.

Substitute to equation y = 3x - 5

22 = 3x - 5

22 + 5 = 3x

27 = 3x

3x / 3 = 27/3

x = 9

The solution is ( 9, 22) for the function y = 3x - 5.
