Question

Find the input (x) of the function y = 3x - 7 if the output
(y) is 5.

Answer 1

The input (x) = 4

Explanation:

Since we know what the output (y) is, you can substitute it into the equation to get:

5 = 3x - 7

Then, solve for x, and you’ll get x = 4. The image below shows step-by-step on how to solve for x.
