Answer:
To solve the expression with the given substitutions, we must first replace each operator with its corresponding substitute:
[ 9 / 8 * 7 + 5 - 10 ]
[ 9 - 8 / 7 * 5 + 10 ]
Now, we perform the operations following the order of operations (PEMDAS/BODMAS):
1. Division and Multiplication:
[tex]8 / 7 \approx 1.142857[/tex]
[tex]1.142857 * 5 \approx 5.714285[/tex]
[tex]9 - 5.714285 \approx 3.285715[/tex]
[tex]3.285715 + 10 = \boxed {13.285715}[/tex]
[tex]13.285715[/tex]
