Answer:
Andre started with the number 7.
Step-by-step explanation:
We are given the following information in the question:
A number puzzle:
" Pick a number Add 2 Multiply by 3 Subtract 7 Add your original number Andre’s final result is 27."
Let x be the starting number. Ten, we can write:
Pick a number and add 2:
[tex]x+2[/tex]
Multiply by 3:
[tex]3(x+2)[/tex]
Subtract 7
[tex]3(x+2)-7[/tex]
Add your original number
[tex]3(x+2)-7+x[/tex]
The final result is 27.
[tex]3(x+2)-7+x = 27\\3x + 6-7+x = 27\\(3x+x) + (6-7) = 27\\4x - 1 = 27\\4x = 28\\x = 7[/tex]
Thus, the number Andre started with was 7.
