Question

Решить уравнение 4z+4z+5=0

Answer 1

4z+4z+5=0
8z= -5
z= -5:8
z= -0,625
ОТВЕТ: -0,625

Answer 2

4z+4z+5=0
4z+4z=-5
8z=-5
z=-5/8
z=-0,625

Answer 3

To solve the equation 4z + 4z + 5 = 0, you need to combine like terms and then isolate the variable z on one side of the equation. Let's simplify the equation step by step:

Step 1: Combine like terms on the left-hand side of the equation. 4z + 4z + 5 = 8z + 5

Step 2: Set the expression equal to zero. 8z + 5 = 0

Step 3: Isolate z on one side of the equation by moving the constant term to the other side. Subtract 5 from both sides of the equation. 8z = -5

Step 4: Finally, solve for z by dividing both sides by 8. z = -5/8

So, the solution to the equation is: z = -5/8
