Answer 1

Answer:

9z-15 = 9-3z

collect the like terms

9z+3z = 9+15

12z = 24

z = 24/12

z = 2

$\sqrt{2}$

Answer 2

Answer:

The root of the equation 9z-15 = 9-3z is 2.

Step-by-step explanation:

Given the equation, 9z-15 = 9-3z

The root of an equation is the value of the variable that satisfies the equation.

Arranging the like terms of the equation on one side,

$9z+3z = 9+15$

Adding the terms on both sides,

$12z = 24$

Dividing both sides of the equation by 12,

$\frac{12z}{12} = \frac{24}{12}$

$\implies z = 2$

If we place z=2 in the given equation, it satisfies the equation.

Therefore, the root of the equation 9z-15 = 9-3z is 2.
