solve.
5(z + 3)=35

Explanation:

Step1: Apply distributive property

$5(z + 3)=5z+15$. So the equation becomes $5z + 15=35$.

Step2: Subtract 15 from both sides

$5z+15 - 15=35 - 15$, which simplifies to $5z=20$.

Step3: Divide both sides by 5

$\frac{5z}{5}=\frac{20}{5}$, so $z = 4$.

Answer:

$z = 4$
