Answer

Explanation:

Step1: Set up equations

Let $w$ be the number of weeks. Sam's money $S = 20 + 5w$, Alex's money $A=40 + 3w$.

Step2: Set the two - equations equal

$20 + 5w=40 + 3w$.

Step3: Solve for $w$

Subtract $3w$ from both sides: $20 + 5w-3w=40 + 3w-3w$, which gives $20 + 2w=40$. Then subtract 20 from both sides: $20-20 + 2w=40-20$, so $2w = 20$. Divide both sides by 2: $w=\frac{20}{2}=10$.
