What will be the result of this algebraic expression:

$5x-6$

if we place

$x=-2$

Step-by-step solution

To solve this problem, we will evaluate the algebraic expression $5x - 6$ by substituting the value of $x = -2$ into it.

Step-by-step solution:

Step 1: Substitute $x = -2$ into the expression $5x - 6$ . This gives:

$5(-2) - 6$

Step 2: Perform the operations in the expression. Start with the multiplication:

$5(-2) = -10$

Step 3: Substitute the result of the multiplication back into the expression:

$-10 - 6$

Step 4: Now perform the subtraction:

$-10 - 6 = -16$

Therefore, the result of the expression when $x = -2$ is $-16$ .

Comparing this result with the given choices, we conclude that the correct choice is:

$-16$

Final Answer

$-16$
