Answer:
40
Step-by-step explanation:
[tex]x - 1 = 5[/tex]
Solve the equation.
[tex]x = 5 + 1 \\ x = 6[/tex]
Then substitute x = 6 in 8x-8
[tex]8(6) - 8 \\ 48 - 8 \\ 40[/tex]
Or we can do this too. We factor out the expression aka 8x-8 out.
[tex]8x - 8 = 8(x - 1)[/tex]
Because x-1=5, we substitute the expression x-1 as 5.
[tex]8(5) = 40[/tex]
