Question

If 2az-5z=2 then z=?

Answer 1

2az-5z=2

z( 2a - 5) = 2

z = 2/ (2a -5)

Answer 2

can u explain what you did please

Answer 3

1. 2az-5z=2 ---> the problem

2. To solve for z, then the z terms have to be collected on one side of the equation.
They are already collected on one side.

3. Factor out the z term.

z ( 2a - 5) = 2

4. Think of this as a coefficient times a variable.

as in (2a - 5) * z = 2

[Note: If we had 7Z = 2, the answer would be z = 2/7.]

We will do the same for (2a - 5) * z = 2.

5. z = 2 / (2a - 5)

Note that solving for z means there are no z terms in the solution for z.
