solve for z.\n2(5 + z) = 16\nz = ?

Answer:

$z = 3$

Explanation:

Step1: Expand the left - hand side

$2(5 + z)=10 + 2z$ So the equation becomes $10+2z = 16$.

Step2: Isolate the term with $z$

Subtract 10 from both sides: $2z=16 - 10$. $2z = 6$.

Step3: Solve for $z$

Divide both sides by 2: $z=\frac{6}{2}$. $z = 3$.
