The number Lola is thinking of is 5.
Solución
Solve the equation \( 79x+9=404 \).
Solve the equation by following steps:
- step0: Solve for \(x\):
\(79x+9=404\)
- step1: Move the constant to the right side:
\(79x=404-9\)
- step2: Subtract the numbers:
\(79x=395\)
- step3: Divide both sides:
\(\frac{79x}{79}=\frac{395}{79}\)
- step4: Divide the numbers:
\(x=5\)

The Deep Dive
First, let's work backwards! Since you get 202 after dividing by 2, multiply 202 by 2 to get 404. Next, subtract 9 from 404, which gives you 395. Finally, to find Lola's number, divide 395 by 79, leading you to the conclusion that Lola's number is 5. So, Lola is thinking of the number 5!
