Solve for z. 9 = 5 + 2z z = _____

Isolate variable z: Isolate the term with the variable z. To isolate the term with z, we need to move the constant term (5) to the other side of the equation by subtracting 5 from both sides. Calculation: 9 - 5 = 5 + 2z - 5 This simplifies to: 4 = 2zSolve for z: Solve for z. Now that we have 2z on one side, we can find z by dividing both sides of the equation by 2. Calculation: 4 / 2 = 2z / 2 This simplifies to: 2 = z
