$s=11$
We start with the given equation: $7(s-5)=42$ We expand the left side of the equation using the distributive property: $7s-35=42$ We then add $35$ to both sides of the equation: $7s-35+35=42+35$ Next, we combine like terms: $7s=77$ Finally, we divide by $7$ on both sides of the equation: $s=\frac{77}{7}=11$
