Evaluate the Expression 5x-6 When x Equals -3: Step-by-Step Solution

Question

What will be the result of this algebraic expression:

$5x-6$

if we place

$x=-3$

The first step is to substitute X in the exercise, resulting in:

$5(-3)-6$

When we have two numbers with different signs, meaning one number is negative and the other is positive or vice versa,

the result of multiplication or division will always be negative.

$5\times-3=-15$

$-15-6=-21$

$-21$
