Answer 1

My answer is in the following picture, hopes it can help you ~

Answer 2

One solution.

Explanation:

We have been given an equation
`20z-5-12z=10z+8`. We are asked to find the number of solutions for our given equation.

Let us solve our given equation. Upon combining like terms, we will get:

`20z-12z-5=10z+8`

`8z-5=10z+8`

`8z-10z-5=10z-10z+8`

`-2z-5=8`

`-2z-5+5=8+5`

`-2z=13`

`(-2z)/(-2)=(13)/(-2)`

`z=-(13)/(2)`

Therefore, our given equation has only one solution.
