= - 48-63= - 111

Answer 2

Finding the Value of an Expression

To find the value of the expression \(x - 7(x + 9)\) when \(x = 8\), we can simply substitute \(x = 8\) into the expression and perform the arithmetic.

Substitute \(x = 8\) into the expression: \[8 - 7(8 + 9)\]

Perform the arithmetic: \[8 - 7(17)\] \[8 - 119\] \[-111\]

So, the value of the expression \(x - 7(x + 9)\) when \(x = 8\) is -111.
