Answer 1

Step 1

Given:

`-8(x-1)=-40`

Required: To give reasons for each step

Step 2

`(-8(x-1))/(-8)=(-40)/(-8)---(Division\text{ property of equality)}`

Step 3

`x-1=5-----(\text{simplifying)}`

Step 4

`x-1+1=5+1-----(\text{Addition property of equality)}`

Step 5

`x=6----(\text{Simplifying)}`
