Question

solve for z. 2(5 + z) = 16 z = ?

Explanation:

Step1: Expand the left - hand side

$2\times5+2z = 16$, which simplifies to $10 + 2z=16$.

Step2: Isolate the term with z

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

Step3: Solve for z

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

Answer:

$z = 3$
