Let's translate this from words to equations: So (4x+1) / 3=7 is our first equation. Multiply by 3, subtract 1, then divide by 4 to get x. Notice it is the exact opposite of what Joe did to get back to where he started. Once you get x, just follow the instructions, so divide by 3, add 1 and multiply by 4. You will end up with a fraction since the original number is not evenly divisible by 3.
